Question

Predict how many times you would expect to land on a 5 if you roll a standard number cube 36 times.

Answer 1

6

Explanation:

The probability of getting a '5' on one toss is 1/6. Thus, if you roll the cube 36 times, the predicted number of '5's will be 36(1/6) = 6

Answer 2

Since we're dealing with probability, you have a 1/6 chance to land the dice on 5. and since 6 is a multiple of 36, we can conclude that

1/6 = ? / 36

6 x 6 = 36

6 x 1 = 6

Answer: you should approximately roll a 5 about 6 times
