If a number x is chosen from the numbers 1, 2, 3, and a number y is selected from the numbers 1, 4, 9. Then, P (xy < 9)

Total numbers of elementary events are: 3 x 3 = 9

Let E be the event of (xy < 9)


Favorable outcomes are: 1× 1 =1, 1×4 = 4, 2×1 =2, 2×4= 8, 3×1 =3


Numbers of favorable outcomes are: 5


P (xy < 9) = 5/9
