Answer:

The probability of getting two 4s is 5.55%.

Step-by-step explanation:

Since fair says is rolled four times, to calculate the probability of obtaining exactly two 4s the following calculations must be performed:

100/6 = 16.6666

0.166666 x 0.166666 = X

0.02777 = X

1 = 100

0.02777 = X

0.02777 x 100 = X

2.77 = X

2.77 x 2 = 5.55

Therefore, the probability of getting two 4s is 5.55%.
