# Following cards are put facing down:

A E I O U

What is the chance of drawing out

(a) a vowel

(b) A or I

(c) a card marked U

(d) a consonant

**Solution:**

Given, A E I O U are the cards put facing down.

Chance of drawing a card = number of favourable card/total number of cards

(a) We have to find the chance of drawing out a vowel.

Favoruable card = A, E, I, O, U

Number of favourable card = 5

Total number of cards = 5

Chance of drawing out a vowel = 5/5 = 1

Therefore, the chance of drawing out a vowel is 1.

(b) We have to find the chance of drawing out A or I.

Favoruable card = A, I

Number of favourable card = 2

Total number of cards = 5

Chance of drawing out a vowel = 2/5

Therefore, the chance of drawing out A or I is 2/5.

(c) We have to find the chance of drawing out a card marked U.

Favoruable card = U

Number of favourable card = 1

Total number of cards = 5

Chance of drawing out a vowel = 1/5

Therefore, the chance of drawing out a card marked U is 1/5

(d) We have to find the chance of drawing out a consonant.

Favoruable card = cards without vowel

Number of favourable card = 0

Total number of cards = 5

Chance of drawing out a vowel = 0/5 = 0

Therefore, the chance of drawing out a consonant is 0.
