Question

Two natural numbers are selected at random find the probability that their sum is divisible by 10

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Probability that their sum is divisible by 10

Answer:

10%

Step-by-step explanation:

Since number of natural number exist = infinite

but the number of natural number divisible by 10 = 10%

If we select two natural number at random,then the number may be any natural number

and their sum may be divisible by 10 or may not be divisible by 10.

But according to condition sum should be divisible by 10 and number of natural number available which is divisible by 10 is approximately 10%

Hence its probability will be 10%
