Question

The probability that Ali wins a chess game is 0.4. Given that he plays only 5 games in a week, find the probability that in any week he wins exactly 4 games by using binomial distribution table

Answer 1

\[b(n; x; p) =(n!/x!(n-x)!)P ^{x}q ^{n-x}\]

Answer 2

\[n=5, p=0.4, x=4, q=1-p=0.6\]

Answer 3

n = number of times you repeat the experiment
p = probability of success during each trial
q = 1 p = probability of failure
X = number of successes
