Question

Rachel plays a game by rolling two number cubes with side's numbered 1 through 6. To win the game, the sum of the numbers facing up must be 11. What is the probability that Rachel will win the game

Answer 1

1/18

Explanation:

Answer 2

The probability that Rachel will win the game p(E) = 1/18 =0.055

Explanation:

Explanation:-

Let "E" be the event of getting sum 11 on the two cubes with sides numbered through 1 to 6 so the number of favorable cases to E = { (6,5), (5,6)}

n(E) =2

The total number of exhaustive cases n(s) = 6^2 =36

Probability P(E) =
`(number of favorable cases)/(total number of exhaustive cases.)`

The probability that Rachel will win the game

`P(E) = (2)/(36) = (1)/(18) =0.055`

The probability that Rachel will loose the game

`P(E)^(-) = 1-P(E)`

= 1 - 0.055 = 0.945
