A bag contains cards numbering from 5 to 25. One card is drawn from the bag. Find the probability that the card has numbers from 10 to 15.

A bag contains card numbered from 5 to 25.Total number of cards in the bag = 21Total number of possible outcomes = 21Now, number of cards bearing the number from 10 to 15 = 6Number of favourable outcomes = 6Required probability = Number of favourable outcomesTotal number of possible outcomes = 621 = 27

total number of outcomes = 21             - ( from 5 to 25 )

total number of favourable outcomes = 6                  - ( from 10 to 15 

P(E) = 6/21
