2. (a) A radioactive source emits 7 alpha particles on average every 5 milliseconds. X is the random variable that counts the number of alpha particles emitted by the source during a 12 millisecond interval. It has a Poisson distribution. Calculate P(x > 15). (b) Y is a random variable with the Poisson distribution. P(Y = 3) equals 36 times PCY = 0). Find P(Y = 2).
