In a game the player wins if he rolls a 6 on a number cube. If the number cube is rolled 18 times, then what is a reasonable prediction for the number of unsuccessful rolls?

Respuesta :

On a number cube, your chance of getting a 6, is 1/6 and the chances of NOT getting.m a 6 is 5/6.

In 18 rolls (3 groups of 6), the chances of NOT getting a 6 would be 15/18 rolls.

This is a reasonable prediction of how many unsuccessful rolls.
