total no of outcomes=113
S=11,13,17,19,23,29
probability=6/113
S=11,13,17,19,23,29
probability=6/113

All possible outcomes are 11, 12 ,13.............123.
Number of all possible outcomes=(123-10)=113
Let E be the event that the number on the drawn card is the prime number less than 30.
Then favourable outcomes are 11 ,13 ,17 ,19 ,23 29.
so, the of favourable outcome =6
therefore P( E )=6/113.
