Consider an experiment with a deck of 52 playing cards, in which there are 13 cards in each suit, two suits are black, and two s

uits are red. Suppose E1 = the outcome is a red card and E2 = the outcome is a face card (K, Q, J). Determine P(E1 or E2).

Answer:

<u>P (E1) = 1/2 or 50%</u>

<u>P (E2) = 3/13 or 23%</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of playing cards = 52

Number of suits = 4

Number of cards per suit = 13

Number of black suits = 2

Number of red suits = 2

2.  Suppose E1 = the outcome is a red card and E2 = the outcome is a face card (K, Q, J). Determine P(E1 or E2).

P (E1) = Number of red cards/Total of playing cards

P (E1) = 26/52 = 1/2 = 50%

P (E2) = Number of face cards/Total of playing cards

P (E2) = 12/52 = 3/13 = 23%

Answer:

outcomes of E1 = [1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36]

outcomes of E2 = [1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35]

Nice of you to offer 50 points

the constant of proportinality is the sloep or
\frac{change(y)}{change(x)}
x is independent variable and y is dependent variable

the independent variable influences the value of the dependent variable

in this case, the number of months influences the amount of money saved

to find the slope, you do
x=number of months
y=amount

we have
4months, $50
8 months, $100
18 months, $225

or
(x,y)
(4,50)
(8,100)
(18,225)

we can compare

the slope between the points (a,b) and (c,d) is
(d-b)/(c-a)
we can take the slope between any 2 points (assuming the slope is the same, which it is)

(4,50) and (8,100)
slope=(100-50)/(8-4)=50/4=25/2=12.5

the slope is 12.5

sleet_krkn [62]

Answer:

b. 0.45.

Step-by-step explanation:

The total possible outcome of a probability is 1

Given;

Probability that both lights will be red when she reaches them = 0.22

Probability that the first light will be red and the second light will not be red = 0.33

Probability that the second light will be red when she reaches it = x

These are all the possible outcomes, therefore

0.22 + 0.33 + x = 1

0.55 + x = 1

x = 1 - 0.55

x = 0.45

aliya0001 [1]
20 minutes on passing .....40 minutes on shooting

ratio of time spent on shooting to passing....
these are not hard, u just have to pay attention to the wording...

the ratio of shooting to passing is 40/20 which reduces to 2/1 or 2:1 or
2 to 1 <===

but if it would have asked for passing to shooting, it would have been :
20/40 which reduces to 1/2 or 1:2 or 1 to 2

so ur answer is 2/1 or 2:1 or 2 to 1

I dont understand what the question is asking me​
kipiarov [429]

Answer:

\huge\boxed{\sf

Step-by-step explanation:

∠E = 1/2 (mCD - mAB)

<u>Where mCD = 110° and mAB = 30°</u>

∠E = 1/2 (110° - 30°)

∠E = 1/2 (80°)

∠E = 40°

\rule[225]{225}{2}

Hope this helped!
