A number x is selected at random from the numbers 1, 2, 3 and 4. Another number y is selected at random from the numbers 1, 4, 9 and 16. Find the probability that product of x and y is less than 16.
Possible outcomes are { 1, 4, 9, 16, 2, 8, 18, 32, 3, 12, 27, 48, 36, 64}
Favorable outcomes i.e. product less than 16 { 1, 2, 3, 4, 8, 9, 12, }
Let E be the event getting the product less than 16 then,
