Question 878441: Hi,please help me with this question as I have a test tomorrow
A card is drawn from a standard deck and replaced. If this experiment is repeated 30 times, what is the probability that
(a) exactly 10 of the cards are spades?
(b) no more than 5 cards are spades?
Thankyou!
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
p(spade) = 1/4, n = 30
P(x=10) = 30C10(.25)^10(.75)^20 = .0909
P(x ≤ 5) = binomcdf(30, .25, 5) = .2026
Highly recommend Using TI for cumulative probabilities
