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
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
