(a) From a pack of cards the following cards are kept face down: Suhail wins if he picks up a face card. Find the probability of Suhail winning?

(b) Now the following cards are added to the above cards:

What is the probability of Suhail winning now? Reshma wins if she picks up a 4. What is the probability of Reshma winning? [Queen, King and Jack cards are called face cards.]

**Solution:**

(a) There are 7 cards in total I which 1 is face card and 6 are number cards

For suhail to win, he must pick a face card

Probability of getting face card is 1/7

Hence, probability of suhail to win is 1/7

(b) Now if some other cards are also added to existing cards, we have 15 cards in total.

We have 4 face cards

Hence probability of Suhail to win is 4/15

We have 4 cards with 4 written on them.

So, probability of Reshma winning is 4/15
