Step-by-step explanation:
Hi, hope you’re having a good day!
Well,
1st number cube: Second number cube:
6 numbers. 6 numbers
So chances are you will roll 5 probably 1/6..
You might also roll an even number 3/6.
Hope this helped. Thanks.❤️❤️
Answer:
![f=-\frac{6g}{5}](https://tex.z-dn.net/?f=f%3D-%5Cfrac%7B6g%7D%7B5%7D)
Step-by-step explanation:
Given: ![6f + 9g = 3g +f](https://tex.z-dn.net/?f=6f%20%2B%209g%20%3D%203g%20%2Bf)
To solve for the value
we need to isolate it on one side of the equal sign. Let's move the
on the right side to the left side by subtracting it from both sides. We then get:
![5f + 9g = 3g](https://tex.z-dn.net/?f=5f%20%2B%209g%20%3D%203g)
Subtract
from both sides of the equal sign to isolate the ![5f.](https://tex.z-dn.net/?f=5f.)
![5f= -6g](https://tex.z-dn.net/?f=5f%3D%20-6g)
To solve for
we need to divide both sides by
since it is being multiplied by ![f.](https://tex.z-dn.net/?f=f.)
![\frac{5f}{5} =\frac{-6g}{5}\\f=-\frac{6g}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5f%7D%7B5%7D%20%3D%5Cfrac%7B-6g%7D%7B5%7D%5C%5Cf%3D-%5Cfrac%7B6g%7D%7B5%7D)
<u>Answer:</u>
Option c)
The pair does not represent the probabilities of complementary events is 0.25 and 0.50
<u>Explanation:</u>
Probability of complementary events signifies that the sum of the respective probabilities should always add up to 1. That means when the sum of the probability of the individual terms cumulates into 1 then the event performed is a complementary event.
a)Probability of event 1 = 4/7
Probability of event 2 = 3/7
Sum of the events = P(E1) + P (E2)
= 4/7+3/7=7/7=1
Hence it is a complementary event
b)Probability of event 1 = 16% = 0.16
Probability of event 2 = 84%= 0.84
Sum of the events = P(E1) + P (E2)
=0.16+0.84
=1
Hence it is a complementary event
c)Probability of event 1=0.25
Probability of event 2= 0.50
Sum of the events = P(E1) + P (E2)
= 0.25+0.50
=0.75
Since the sum is not 1
Therefore it is not a complimentary event
d)Probability of event 1= 1
Probability of event 2= 0
Sum of the events = P(E1) + P (E2)
= 1+0
=1
Hence it is a complimentary event

Answer: The value of P(A or B) is 0.8.</h3>
Step-by-step explanation: We are given P(A)=0.6 , P(B)=0.3 and P(A and B)=0.1.
P(A and B)=0.1 could be written as P(A∩B) = 0.1.
We need to find P(A or B) that is P(A∪B) = ?
We know formula,
P(A∪B) = P(A) + P(B) - P(A∩B)
Plugging values in formula, we get
P(A∪B) = 0.6 + 0.3 - 0.1
P(A∪B) = 0.9 -0.1
P(A∪B) = 0.8.
<h3>Therefore, the value of P(A or B) is 0.8.</h3>
