Best answer 4 votes 4 votes A fair dice is rolled 10 times, this is repeated independent trials hence it follows Binomial Distribution Probability of getting $6$ = $\frac{1}{6}$ $E(X) = np = 10*\frac{1}{6} = \frac{5}{3}$ Shoto answered Dec 10, 2022 selected Dec 10, 2022 by gatecse Shoto comment Share Follow See all 0 reply Please log in or register to add a comment.
