Question

Suppose you roll a number cube numbered 1 to 6 a total of 200 times. Predict how many times you would expect to roll the number 3.

Answer 1

Answer: 33

Explanation:

Answer 2

Probability of rolling a 3 is 1/6
200 x 1/6 = 200/6
Expectation = 200/6 ie 33.333, 33 to the nearest whole number

So you would expect to roll a three 33 times
