# Following cards are put facing down:

What is the chance of drawing out

A. a vowel

B. A or I

C. a card marked U

D. a consonant

Answer :

(A) a vowel

As the cards are A,E,I,O,U

And all 5 are vowels

Probability =

=

= 1

Means if a card is pulled out it will surely be a vowel

∴ 100% chances are there to get a vowel

(B) The cards pulled out are A or I

Possible outcomes = 2

Total number of outcomes = 5

Probability =

=

= 0.4

∴ It is 40% chances that card will be A or E

(C) The card pulled out is U

Possible outcome = 1

Total number of outcomes = 5

Probability =

=

= 0.2

∴ it is 20% chances of card pulled out to be U

(D) The card pulled out id consonant

As all card are vowels

Possible outcome = 0

Total number of outcomes = 5

Probability =
