Question

A number is selected at random from 1 2 3 and 4 another number y is selected at random from the number 11,4,9 and16. Find the probability that product x and y is less than 16

Answer 1

total numbers of X = 4
Total numbers of Y = 4
so total outcomes =4×4=16
favourable outcomes = less than 16
= (1,11)(1,4)(1,9)(2,4)(3,4)
favourable outcomes = 5
probability = favourable outcomes /totol outcomes
=5/16
