Consider the random variable X that follows an exponential distribution, with μ = 20. The standard deviation of X is σ = . The parameter of the exponential distribution of X is λ = . What is the probability that X is less than 10? P(X < 10) = 0.7981 P(X < 10) = 0.2212 P(X < 10) = 0.4908 P(X < 10) = 0.3935 What is the probability that X is between 30 and 35? P(30 < X < 35) = 0.0493 P(30 < X < 35) = 0.3262 P(30 < X < 35) = 0.2231 P(30 < X < 35) = 0.1738
