If a number 'x' is chosen from the nos. 1,2,3 and number 'y' is selected from the numbers 1,4,9.
Find the probability that xy=10

Open in App

Solution

toal possibilities are
(1,1),(1,4),(1,9),(2,1),(2,4),(2,9),(3,1),(3,4),(3,9)
we can see that none of the out come is favourable for xy = 10
hence the probability is 0
