Question

Following is the probability distribution of a random variable that represents the number of extracurricular activities a college freshman participates in. P(x) 0.06 0.130.45 0.22 0.14 Download data Part 1 Find the probability that a student participates in exactly two activities The probability that a student participates in exactly two activities is 0.45 Part 2 out of 3 Find the probability that a student participates in more than two activities The probability that a student participates in more than two activities is

Explanation / Answer

Solution :

From given probability distribution,

Part 2)

P(x > 2) = P(x = 3) + P(x = 4) = 0.22 + 0.14 = 0.36

P(x > 2) = 0.36

Probability = 0.36
