A letter of English alphabet is chosen at random. Determine the probability that the chosen letter is a consonant.
Let E be the event of choosing an alphabet
Total numbers of alphabets are 26
Then, the favourable outcomes are: B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z
The number of outcomes are =21
∴ P (choosing a consonant) =P (E) = 21/26
