Answer 1

Hello there,

In a game the player wins if you roll a six on a number cube is the number cube is rolled 18 times then what is a reasonable prediction for the number of unsuccessful rolls

Unsuccessful rolls: 14

Answer 2

14 rolls

Explanation:

Each result 1-6 has an equal chance. The probability is the number of chances divided by the total number. The total number of options is 6 since it is a six sided cube. Rolling a 6 which is represented once is a 1 out 6 likelihood.

1 out of 6 is 1/6 = 0.17 = 17%.

This means that 83% of the time will be unsuccessful of 18 rolls.

0.83(17)= 14.11
