Question

1) 2) 3) For a RV X ~ bin(n=5,p=.6) find P(X 1) (1 point) For a RV Y ~ Poisson(A-2) find P(Y=1) (1 point) A telemarketer receives an average of 5 phone calls per hour. Define C as the number of phone calls a telemarketer receives. a) What probability distribution does C follow? Give the name of the distribution and the value of its parameter(s) (2 points). point). (1 point) b) Find the probability a telemarketer receives exactly 6 calls in one hour (1 c) Find the probability that a telemarketer receives at most 1 call in an hour

Explanation / Answer

1) n = 5, p = 0.6

P(X 1) = P(0) + P(1)

P(X 1) = 5C0 * 0.6^0 * 0.4^5 + 5C1 + 0.6^1 * 0.4^4

P = 0.087
