Anna mixes the letters S, E, L, E, C, T, E, and D thoroughly. Without looking, Mary draws one letter. Expressed as a fraction, decimal, and percentage, what is the probability that E will NOT be the letter Mary selects?
There are a total of 8 letters, and 3 of them are E, meaning 5 of them are not E. Mary thus has a 5/8 chance of drawing a letter that is not E. Written as a decimal, that is 0.625, and written as a percentage, that is 62.5%.
