A die is thrown 100 times. If getting an even number is considered a success, then the standard deviation of the number of successes is 5. Explanation: n = 100 p(getting even number) = $\frac{3}{6}$ = $\frac{1}{2}$ q(not even number) = $\frac{3}{6}$ = $\frac{1}{2}$ SD = `sqrt(variance(x)) = sqrt(npq) = sqrt(100 xx $\frac{1}{2}$ xx $\frac{1}{2}$) = sqrt25` = 5
