A bag contains 100 tickets numbered 1, 2, 3, ….100. if a ticket is drawn out at random, what is the probability that the ticket drawn has the digit 2 appearing on it? ........i can't understand plz explain this question

Answered by admin @


Probability = Desired Results / Total Results

In this case, total number of results is 100, as any number from 1 to 100 will come while drawing

The number of Desired Results is 90, as we need a two digit number while drawing which excludes 1, 2,3,4,5, 6,7,8,9,100

Therefore

Probability = 90/100 = 9/10
