Answer to Problem 41E
P(A) = 0.25
Explanation of Solution
Formula:
There need to roll two times. For first and second roll, there is possibility to roll 1,2,3 and 4.
Therefore,
S={(1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (2,4),(3,1), (3,2), (3,3), (3,4),(4,1), (4,2), (4,3), (4,4)}
n(S)=16
So,
n(A)=4
Hence,
