A letter of English alphabet is chosen at random. Determine the probability that the chosen letter is consonant.

Advertisements

Solution

There are 26 letters in English alphabets.

∴ Total number of outcomes = 26

We know that there are 5 vowels and 21 consonants in English alphabets.

∴ Total number of favourable outcomes = 21

∴ Probability that the chosen letter is a consonant = `"Total number of favourable outcomes"/"Total number of outcomes"=21/26`

  Is there an error in this question or solution?

A card is drawn at random from a pack of well shuffled 52 playing cards. Complete the following activity to find the probability that the card drawn is:

Event A: The card drawn is an ace.

Event B: The card drawn is a spade.

Activity: 'S' is the sample space.

∴ n(S) = 52

Event A: The card drawn is an ace.

∴ n(A) = `square`

P(A) = `square`  ......(formula)

∴ P(A) = `square/52`

∴ P(A) = `square/13`

Event B: The card drawn is a spade.

∴ n(B) = `square`

P(B) = `(n(B))/(n(S))`

∴ P(B) = `square/4`
