Question

Sixteen cards are labelled as a, b, c,......m, n, o, p. They are put in a box and shuffled. A boy is asked to draw a card from the box. What is the probability that the card drawn has :A consonant.

Answer 1

Out of 16 cards:

4 Vowels

12 Consonants

$P\left(Vowel\right)=\frac{No.ofVowels}{TotalNo.ofcards}$

$P\left(Vowel\right)=\frac{4}{16}=\frac{1}{4}=0.25$

$\therefore P\left(Consonant\right)=1-P\left(Vowel\right)=1-0.25=0.75$
