consider the following binomial experiment: 290 people have been exposed to the flu. if the probability that a person contracting the flu on exposure is 0.37, find the variance of these 290 people contracting the flu. a) 182.7000 b) 39.7010 c) 0.2331 d) 67.5990 e) 493.7838 f) none of the above.

varianceof the 290 peoplecontacting the flu, given the probability of contacting the flu, is d) 67.5990## How to find the variance ?

probabilityin abinomial experiment,and the number of people in the experiment, you can find the variance by the formula:contactingtheflu= 0.37varianceof the people contacting the flu is:= 290 x 0.37 x ( 1 – 0.37)
