Suppose a "hot spot" is a site with a reading of 40 or higher.

(a) In a binomial setting, let us call success a "hot spot." Use Table A to find p = P(success) 5 P(40 ( x) for a single trial.

(b) Suppose you decide to take readings at random until you get your first "hot spot." Let n be a random variable representing the trial on which you get your first "hot spot." Use the geometric probability distribution to write out a formula for P(n).

(c) What is the probability that you will need more than four readings to find the first "hot spot"? Compute P(n > 4).
