Question

Pip rolls a fair dice 168 times. How many times would pip expect to roll a one

Answer 1

28

Explanation:

Using the formula:

Mean = np

n = number of rolls = 168

p = probability of obtaining a 1 from a die roll

P = number of 1 / total Faces

P = 1/6 = 0.16667

Mean = 168 * 0.16667

Mean = 28
