Question 50

A fair four-sided die is labelled with the numbers 1, 2, 3 and 4. The die is rolled 50 times and the score, $S$ , for each roll is recorded.

Find the mean and the variance of $S$ .

[3]

Using the Central Limit Theorem, find an approximation for the probability that the mean of the 50 scores is greater than 2.8.
