✵ Question ✵

A pack of 26 cards bear 26 alphabets of English. A card is drawn at random. What is the probability that it bears:

a) vowel?

b) letter which is used in writing "GEOGRAPHY" ?

✵ To find ✵

The probability that the alphabet is

a) vowel.

b) used in writing ✵ Question ✵

A pack of 26 cards bear 26 alphabets of English. A card is drawn at random. What is the probability that it bears:

a) vowel?

b) letter which is used in writing "GEOGRAPHY" ?

✵ To find ✵

The probability that the alphabet is

a) vowel.

b) used in writing "GEOGRAPHY".

✵ Solution ✵

No. of vowels in English alphabet

= 6

Probability

= No. of vowels / Total alphabets

= 5/26

= .

✵ Solution ✵

Probability that is bears a vowel→

No. of vowels in English alphabet

= 6

Probability

= No. of vowels / Total alphabets

= 5/26

Probability that it bears a letter used in "GEOGRAPHY"→

No. of letters in "GEOGRAPHY"

= 8

Probability

= No. of letters / Total alphabets

= 8/26

= 4/13

✵ Hence ✵

a) Probability that is bears a vowel is 5/26.

b) Probability that it bears a letter used in "GEOGRAPHY" is 4/13.

✵ Therefore ✵

The answer of a) is 5/26 and that of  b) is 4/13.
