Question

A number x is selected at random from the numbers. Another number y is selected at random from the numbers 1,4,7,9. Find the probability that the product of x and y is less than 16..
Plz tell me one thing that the elements in the favourable outcomes are repeated or not....
Step by step explanation....

Answer 1

Answer:

Step-by-step explanation:

here,

x can be 1,4,7,9

y can be 1 ,4,9,16

∴ total no. of  cases of xy= 16

no. of cases where product of x and y is less than 16 =8(1,4,9,2,8,3,12,4)

required probability=8/16=1/2
