What is Probability of Marathon Times about?

Here are the steps to solve this binomial probability problem: 1) Identify the key parameters: p = probability of success on each trial = 0.05 n = number of trials = 20 x = number of successes = 1 2) Use the binomial probability formula: P(X ≤ 1) = P(X = 0) + P(X = 1) = C(n,x) * p^x * (1-p)^(n-x) 3) Calculate: P(X = 0) = C(20,0) * 0.05^0 * (1-0.05)^20 = 0.4096 P(X = 1
