X is a random variable with an exponential distribution with parameter = .7 Thus the cdf

Question:

X is a random variable with an exponential with parameter λ = .7 Thus the cdf of X is f(x) = .7 e−.7 x for x ≥ 0.
d) Calculate the probability that X > 6. Use the pexp function
e) Calculate the probability that X is at least 1 more than its expected value.
