The letters of the alphabet are written on 26 cards. Two cards are chosen at random without replacement. What is the probability that at least one of them is a consonant

The probability of selecting at least one consonant when selecting 2 cards is 0.0954.

Step-by-step explanation:

There are 26 letters in the English alphabet series.

Of these 26 letters there are 5 vowels and 21 consonants.

The total number of ways to select 2 letters is:

The number of ways to select at least one consonant is:

n (At least 1 consonant) = N - n (Two vowels)

Compute the probability of selecting at least one consonant as follows:

Thus, the probability of selecting at least one consonant when selecting 2 cards is 0.0954.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

the answer is 8/21
