Answer 1

Part 1. Probability of choosing the letter A:

There are 5 A's in the phrase "THE UNITED STATES OF AMERICA" and a total of 28 letters.

P(A) = 5/28 ≈ 0.178

Part 2. Probability of choosing a consonant:

There are 15 consonants in the phrase "THE UNITED STATES OF AMERICA" and a total of 28 letters.

P(consonant) = 15/28 ≈ 0.536

Part 3. Probability of choosing a letter from the word "of":

There are 2 letters in the word "of" and a total of 28 letters.

P(letter from 'of') = 2/28 ≈ 0.071
