The probability that the sum of Michelle's rolls is 4 is 0.083 ∴ P(A)=0.083 Step-by-step explanation: Given that Michelle is rolling two six-sided dice, numbered one through six. To find the probability that the sum of her rolls is 4:
∴ n(s)=36 Let P(A) be the probability that the sum of her rolls is 4 Then the possible rolls with sums of 4 can be written as
n(A)=3 The probability that the sum of her rolls is 4 is given by
=0.083 ∴ P(A)=0.083 ∴ the probability that the sum of Michelle's rolls is 4 is 0.083
