The variance of the 290 people contacting the flu, given the probability of contacting the flu, is d) 67.5990
When given the probability in a binomial experiment, and the number of people in the experiment, you can find the variance by the formula:
= Number of subjects in experiment x Probability of contacting the flu x ( 1 - probability of contacting the flu)
Number of subjects in experiment = 290 people
Probability of contacting the flu = 0.37
The variance of the people contacting the flu is:
= 290 x 0.37 x ( 1 - 0.37)
= 290 x 0.37 x 0.63
= 67.5990
