Question

In a game a player wins if he rolls a 6 on a number cube if the number cube is rolled 18 times then what is an reasonable prediction for the number of unsuccsecful rollls

Answer 1

the reasonable prediction for the number of unsuccessful rollls is 15 ÷ 18

Explanation:

The computation of the number of unsuccessful rolls is as follow:

For a number cube, the probability of getting 6 would be 1 ÷ 6 and for not getting is 5 ÷ 6

Now for 18 rolls i.e. there is 3 group of 6 so the chance of not getting would be 15 ÷ 18

Hence, the reasonable prediction for the number of unsuccessful rollls is 15 ÷ 18

The same is to be considered
