Answer:
a) Threfore, the probability is P=0.337.
b) Threfore, the probability is P=0.77481.
Step-by-step explanation:
We know that the probability that the average player wins a hand is about 45%. Assume each hand is independent.
a) We calculate the probability that the average player wins twice in 5 hands.
We know that p=0.45 ⇒ q=1-0.45=0.55
Threfore, the probability is P=0.337.
b) We calculate the probability that the average player wins ten or more times in 25 hands. We get
Threfore, the probability is P=0.77481.
