Solution

The correct option is B

1/15


Number of couples who remain unmarried = 60 - 15 - 25 - 16 = 4

Total number of couples in a village = 60

Probability that a couple will remain unmarried = Number of couples who remain unmarriedTotal number of couples

So, probability of a couple to remain unmarried =460 =115
