Question

A number x is selected from the numbers 1,2,3 and then a second number y is randomly selected from the numbers 1,4,9. What is the probability that the product xy of the two numbers selected will be less than 9? Please answer urgent need.

Answer 1

Answer: $\dfrac{5}{9}$

Step-by-step explanation:

Given : A number x is selected from the numbers 1,2,3 and then a second number y is randomly selected from the numbers 1,4,9.

Total number of outcomes for product of two numbers selected from x any :

3×3=9

The outcomes for which the product xy of the two numbers selected will be less than 9 :  1×1 , 1×4, 2×1, 2×4, 3×1

Hence, the number of desired outcomes = 5

Then, the probability that the product xy of the two numbers selected will be less than 9 :-

$\dfrac{\text{Desired outcome}}{\text{Total outcomes}}\\\\=\dfrac{5}{9}$
