Question

How many time will I get a two when I roll a dice 300 times?

Answer 1

50 times, assuming it is a fair dice.

Explanation:

We know if we roll a dice we have 6 different possibilities, 1 through to 6. Therefore we have a 1/6 chance of getting a 2. This means if we roll a dice 6 times we should realistically get a 2 once.
Therefore to find the number of times we get a 2 in 300 rolls we must multiply 300 by 1/6. As a result this means we should get a 2 50 times assuming the dice is a fair dice.
