Question

Blake randomly chose a letter from alphabet.

What is the probability that this letter has at
least one line of symmetry, given that it is a
consonant?

Answer 1

Hey there!

The letters B, C, D, H, K, M, T, V, W, and X have at least one line of symmetry.

A, E, I, O, U and Y are the vowels.

So we have a total of 21 consonants, and 10 are symmetrical.

Thus, the probability is 10/21.

Let me know if this helps :)
