17 cards numbered 1,2,3....., 17 are put in a box and mixed thoroughly. One person draws a card from the box. Find the probability that the number on the card is: (i)odd (ii) a prime(iii) divisible by 3 (iv)divisible by 3 and 2 both

Explanation

(1) Event (A prime number)=`[2,3,5,7,11,13,17]=7`


Probability=`8/(17)`


(2)Event( Number divisble by `3`)=`[3,6,9,12,15]=5`


probability`=5/(17)`
