Question

What is the probability that the sum of the digits of a 10-digit number is divisible by 10?​

Answer 1

Step-by-step explanation:

Given What is the probability that the sum of the digits of a 10-digit number is divisible by 10?  

• Probability = Favourable outcome / Total number of outcomes
• Now all possible outcomes will be 9000000000 (because there are 1 x 10 ^9 to 9 x 10^9)
• So favourable outcome will be 9000000000 / 10 (because the number has to be divisible by 10 and the last digit should be 0)
• So probability = 9 x 10^8 / 9 x 10^9
•                       = 1 / 10
•                      = 0.1
