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

lakkis [162]

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%

Joe spends $8 for lunch and $6.50 for dry cleaning. He also buys 2 shirts that cost the same amount. Joe spends a total of $52.

2shirts=52-8-6.50=37.50

so each shirt costs 18.75$

The mail arrival time to a department has a uniform distribution over 5 to 45 minutes. What is the probability that the mail arr

VashaNatasha [74]

Answer:

0.5

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X higher than x is given by the following formula.

$P(X > x) = \frac{b - x}{b-a}$

The mail arrival time to a department has a uniform distribution over 5 to 45 minutes.

This means that $a = 5, b = 45$ .

What is the probability that the mail arrival time is more than 25 minutes on a given day?

$P(X > 25) = \frac{45 - 25}{45 - 5} = 0.5$

So the probability that the mail arrival time is more than 25 minutes on a given day is 0.5.
