You mix the letters S, E, L, E, C, T, E, and D thoroughly. Without looking, you draw one letter. Find the probability of not drawing an E as a fraction, a decimal, and a percent.

Fraction = 5/8

Decimal = 0.625

Percentage = 62.5%

Step-by-step explanation:

In this question, we are asked to calculate the probability of not selecting the letter E if we draw a letter from the selection that is spelt SELECTED.

First we should know that the probability of not drawing an E is 1 - probability of drawing an E

Hence, we calculate the probability of drawing an E.

Mathematically, probability of drawing the letter E = number of letter E/ Total number of letters. Total number of letter E is 3. The total number of digits= 8

Probability = 3/8

Now the proof not selecting an E is thus 1 - 3/8 = 5/8

As a decimal, this is 0.625. As a percentage, that would be 62.5%
