Question

The sum of two positive numbers is 10 . The probability that their product is greater than 20 is

Answer 1

This is your answer 10-0

Answer 2

P(getting the product of two numbers greater than 20)$=\dfrac{5}{11}$

Step-by-step explanation:

Given,

The sum of two positive numbers = 10

To find, the probability that their product is greater than 20 = ?

All possible outcomes are:

(0, 10), ,(1, 9), (2, 8), (3, 7), (4, 6), (5, 5), (6, 4), (7, 3), (8, 2), (9, 1) and (10, 0)

Total number of all possible outcomes = 11

All favourable outcomes are:

(3, 7), (4, 6),  (5, 5), (6, 4) and  (7, 3)

Number of favourable outcomes = 5

∴ P(getting the product of two numbers greater than 20)=$\dfrac{5}{11}$
