Question

two dice are thrown at the same time and product of numbers appearing on them is noted find the probability that the product is less than 9

Answer 1

hey mate
here's the solution

Answer 2

A = { product less than 9 }
A = { (1,1)(1,2)(1,3)(1,4)(1,5)(1,6)(2,1)(2,2)(2,3)(2,4)(3,1)(3,2)(4,1)(4,2)(5,1)(6,1) }

n(A) = 16 ; n(S) = 36

p(A) = n(A)/n(S) = 16/36 (or) 4/9
