18 times that person have thrown the die if the odds of rolling a certain number on a single die is 1 chance in 6 rolls in the course of a game.
What is probability?
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
The odds of rolling a certain number on a single die is 1 chance in 6 rolls, in the course of a game someone rolled 3 fives according to the odds.
The expected value can be calculated using the expression:
(1/6)n = 3
n is the number of times that person have thrown the die.
n = 18 times
Thus, 18 times that person have thrown the die if the odds of rolling a certain number on a single die is 1 chance in 6 rolls in the course of a game.
