Question

A)

Estimate the probability that on the next roll the score will be 4.
b)
If the dice is rolled 400 times, about how many 2s would you expect to get?​

Answer 1

a) 1/10

b) 110

Explanation:

A) we start by getting the total number of rolls

That would be;

11 + 22 + 7 + 8 + 13 + 19 = 80

The frequency of getting a 4 is 8

The probability that the next roll will be a 4 is;

8/80 = 1/10

b) Firstly, we get the probability of getting a 2

We have this as:

22/80

So for 400 rolls, the number of 2’s will be;

22/80 * 400

= 22 * 5 = 110
