Question

Cards bearing numbers $2,4,6,8,10,12,14,16,18$ and $20$ are kept in a bag. A card is drawn at random from the bag. Find the probability of getting a card which is
(i) a prime number
(ii) A number is divisible by 4.

Answer 1

Given, Cards bearing numbers $2,4,6,8,10,12,14,16,18,20$

(i) Only $2$ is the prime no. out of $10$ numbers

Probability for getting a prime number $=\frac{1}{10}$

(ii) here no such no. which is divisible by $44$

Probability for getting a number divisible by $44=\frac{0}{10}$.
