Compute the probability of each of the following events Roun
Compute the probability of each of the following events:
Round your answers to at least two decimal places.
P(A)=
P(B)=
Solution
Experimeny is rolling two dies
Therefore n(s)=36
Event A: The sum is greater than 8
favourable cases are {(3,6),(4,5),(4,6),(5,4),(5,5),(5,6),(6,3),(6,4),(6,5),(6,6)}
n(A)=10
P(A)=10/36=5/18
Event B:The sum is not divisible by 2 and not divisible by 6.
favourable cases are {(1,2),(1,4),(1,6),(2,1),(2,3),(2,5),(3,2),(3,4),(3,6),(4,1),(4,3),(4,5),(5,2),(5,4),(5,6),(6,1),(6,3),(6,5)}
n(B)=18
P(B)=18/36=1/2
