The probability that skene will be alive in five years time is 3\4 and the probability that is wife will be alive in five years time is 2\5.Find the probability that in five years time both of them will be alive

23/20.

Step-by-step explanation:

given data:

probability that skene would be alive in 5years time = 3/4.

probablility that skene wife would also be alive in 5 years time = 2/5

SOLUTION:

The probability that both would be alive in 5years time.

= 3/4 + 2/5.

= 5*3 + 4*2 /20.

= 15 + 8 /20.

= 23/20.
