There is a probability of 0.06 that a vaccine will cause a certain side effect. Suppose that a number of patients are inoculated with the vaccine. We are interested in the number of patients vaccinated until the first side effect is observed. Use the formula for the sum of a geometric sequence to show that the probabilities in the probability distribution table add to 1.

A.) Define the random variable x?
B.)Verfiy that the setting is geometric?
C.)find the probablity that the 5th patient is the first to expierence the side effect?
D.)How many patients would you expect to vaccinate before the first side effect is observed?
