A probability experiment is conducted in which the sample space of the experiment is Sequals=StartSet 9 comma 10 comma 11 comma

12 comma 13 comma 14 comma 15 comma 16 comma 17 comma 18 comma 19 comma 20 EndSet{9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}​, event Upper F equals StartSet 9 comma 10 comma 11 comma 12 comma 13 EndSetF={9, 10, 11, 12, 13}​, and event Upper G equals StartSet 13 comma 14 comma 15 comma 16 EndSetG={13, 14, 15, 16}. Assume that each outcome is equally likely. List the outcomes in F or G. Find Upper P (Upper F or Upper G )P(F or G) by counting the number of outcomes in F or G. Determine Upper P (Upper F or Upper G )P(F or G) using the general addition rule.

Answer:

From both approaches P(F or G)=0.667

Step-by-step explanation:

P(F or G)=?

F={9, 10, 11, 12, 13}​

G={13,14,15,16}

Finding P(F or G) by counting outcomes in F or G

F or G={9, 10, 11, 12, 13}or {13,14,15,16}

F or G={9, 10, 11, 12,13,14,15,16}

number of outcomes in F or G=n(F or G)=8

S={9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}​

number of outcomes in S=n(S)=12

P(F or G)=n(F or G)/n(S)

P(F or G)=8/12

P(F or G)=0.667

Finding P(F or G) by addition rule

P(F or G)=P(F)+P(G)-P(F and G)

F={9, 10, 11, 12, 13}​

number of outcomes in F=n(F)=5

P(F)=n(F)/n(S)

P(F)=5/12

P(F)=0.417

G={13,14,15,16}

number of outcomes in G=n(G)=4

P(G)=n(G)/n(S)

P(G)=4/12

P(G)=0.333

F and G={9, 10, 11, 12, 13}and {13,14,15,16}

F and G={13}

number of outcomes in F and G=n(F and G)=1

P(F and G)=n(F and G)/n(S)

P(F and G)=1/12

P(F and G)=0.083

P(F or G)=P(F)+P(G)-P(F and G)

P(F or G)=0.417+0.333-0.083

P(F or G)=0.667

Answer:

8/12

Step by step explanation:

The outcomes are the elements in the sample space S={9,10,11,12,13,14,15,16,17,18,19,20}

There are 12 outcomes in this sample space. Since each outcome is equally likely (has equal chance of occurring) then each outcome's probability is 1/12.

(A) the list of outcomes in (F or G) are: (F or G) ={9,10,11,12,13,14,15,16}

(B) P(F or G) = P{9,10,11,...,16}

By counting the number of outcomes in (F or G), P(F or G)=8/12

as there are 8 outcomes in (F or G) and 12 total outcomes in the sample space.

(C) Using addition rule,

P(F or G) = P(F) + P(G) - P(F and G)

P(F) = (1/12 for the outcome 9) + (1/12 for the outcome 10) + (1/12 for the outcome 11) + (1/12 for the outcome 12) + (1/12 for the outcome 13)

P(F) = 5/12

P(G) = 4/12

P(F and G) = probability of having the outcome '13' = 1/12

P(F or G) = 5/12 + 4/12 - 1/12 = 8/12.

If the delivery company achieves its improvement goal, by how much will the hourly delivery rate of the typical delivery staff m
DanielleElmas [232]

It should be noted that the hourly delivery rate is calculated by dividing the income made by the number of hours worked.

<h3>How to calculate the hourly delivery rate</h3>

Your information is incomplete. Therefore, an overview of the information will be given.

In order to get an hourly rate, it's important to divide the income that the person gets by the number of hours that the person worked.

In this case, let's say that the income is $20000 and the number of hours that was worked monthly was 240 hours, the hourly rate will be:

= $2000/240

= $8.33 per hour

A sample of lake water contains 150grams of salt. If 30% of the water sample is salt, find the number of grams the entire sample
hjlf

Answer:

500 grams

Step-by-step explanation:

Let's say that the total number of grams of the sample is x. We know that 30% of x is salt and we also know this quantity is 150 grams. So, we can write this as:

30% * x = 150

Remember that % is simply "out of 100", so 30% = 30/100 = 0.30. Then:

0.30 * x = 150

Divide both sides by 0.30:

x = 500 grams

Hope this helps!

Pls help me with this question
Sedbober [7]

7/12,  3/4,  4/7,  5/8,  4/7

Answer:  

Order from Least to Greatest

4/7    =       4/7     <       7/12    <    5/8   <   3/4  

Showing Work  

Rewriting as fractions if necessary:  

7/12, 3/4, 4/7, 5/8, 4/7  

The least common denominator (LCD) is: 168.  

Rewriting as equivalent fractions with the LCD:  

98/168, 126/168, 96/168, 105/168, 96/168  

Ordering these fractions by the numerator in order from least to greatest:  

96/168    =    96/168     <     98/168    < 105/168    < 126/168  

Therefore, your input in order from least to greatest is:

Answer   =======>   4/7    =   4/7    <    7/12    <     5/8    < 3/4


B):  1.35,   5/4,   1.349,  6/5, 7/6

Number of inputs ====>  5

Answer => Ascending Order:  Least to Greatest =====>  7/6, 6/5, 5/4, 1.349, 1.35



C):   0.819,  0.8199, 81/100, 815/1000

Number of Inputs  ======>    4

Answer  ==> Ascending order (Least to Greatest ====>    81/100, 815/1000, 0.819, 0.8199



D):    3  4/7, 245/70, 3.572, 90/29

Number of Inputs:  4

Answer ==>  Ascending Order(Least to Greatest) ==> 90/29, 245/70, 3.572, 3 4/7




Hope that helps!!!!                                              : )
