Question

(1 point) In the game of blackjack as played in casinos, the dealer has the advantage (surprisel). Most players do not play very well. As a result, the probability that the average player wins a hand is about 0.3. Find the probability that an average player wins A. twice in 5 hands. Probability 3087 B. 2 or more times in 10 hands Probability8506916541 unz There are several books that teach blackjack players the "basic strategy" which increases the probability of winning any hand to 0.35. Assuning that the player plays the basic strategy, find the probability that he or she wins C. twice in 5 hands Probability D. 2 or more times in 10 hands.

Explanation / Answer

Ans:

C)Binomial distribuion with n=5,p=0.35

P(twice)=5C2*0.35^2*(1-0.35)^3

=0.3364

D)Binomial distribuion with n=10,p=0.35

P(2 or more)=1-P(1 or less)

=1-0.6510-10C1*0.35^1*0.65^9

=1-0.0135-0.0725

=0.9140
