Question

Suppose you rolled the two number cubes 100 times, would you expect at least one 3 more or less than 34 times? Explain.

Thanks!~~ :3

Answer 1

The possible outcomes are listed in the table below. The probability to get at least one three is 11 out of 36. If the cubes rolled 100 times, then the probability of getting at least one is

$\frac{11}{36}$×100=30.6 (1 dp) which is less than 34
