Question

A bag content 100tickets numbered 1,2,3,...100if a ticket is drawn at random what is the probability than the ticket drawn has the digit 2 appearing on it

Answer 1

Hey Buddy

Here's the answer

_________________________

# Total no of tickets = 100

# no of tickets having digit 2

=> from 1 to 9 = { 2 } = 1

=> from 10 to 19 = { 12 } = 1

=> from 20 to 29 = { 20,21,22,23,24,25,26,27,28,29 } = 10

=> from 30 to 100 = { 32,42,52,62,72,82,92 } = 7

Now total no of having digit 2

=> 19

So

=> Probability = fav. outcome / total outcome

=> Probability = 19 / 100
