Question

A number is
1, 2, 3, 4 and then second number 'y'
is selected from the
number
1,4,9
What is the
probability that
the product
xy
Is
less than 9​

Answer 1

Answer: \dfrac{5}{9}

9

5

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 :-

\begin{lgathered}\dfrac{\text{Desired outcome}}{\text{Total outcomes}}\\\\=\dfrac{5}{9}\end{lgathered}

Total outcomes

Desired outcome

=

9

5
