Find a) the probablity that a either 2, 3, or 4 appears each time, and b) the probability that a 3 never appears. Give your answers as fractions. 5 Five cards are dealt at random from a regular deck of 52 playng cards. F a) the probability that exactly 3 are diamonds, and b) the probability that all 5 cards are of the same suit. e your answers as fractions.

Explanation / Answer

Question 3

It is a wrong question as it is not given how many balls are drawn.

Question 4

Tossed 3 times

(a) Here Pr(2,3 or 4 appears) = 3/6 = 0.5

So, Pr(2,3 or 4 appears in 3 attempts) = 0.53 = 0.125

(b) Pr(3 dont occur in one roll) = 1 - 1/6 = 5/6

Pr(3 never occurs in 3 rolls) = (5/6)3 = 125/216

Question 5

Five cards are drawn from 52 regular playing cards.

(a) Pr(Exactly 3 diamonds) = 13C3 * 39C2/ 52C5 = 0.0815

(b) Pr(all 5 cards are of same suit) = 4 * 13C5/52C5 = 0.00198
