Question

A machine generates two digit numbers Randomly find the probability that the number is greater than 87

Answer 1

Step-by-step explanation:

2-digit numbers : 10, 11, 12, 13, 14, . . . . . . . . . . . 99

Total no. of 2-digit numbers = 90

Total no. of favourable numbers = 12

Probability =  Favourable Outcome / Total Outcome

Probability = 12 / 90

                       2 / 15

The probability is 2/15.
