The table shows the probabilities of selecting a vowel (A, E, I, O, U) from a page in a book. To find the probability that a random letter is not a vowel, we first need to sum the probabilities for all the vowels and subtract that total from 100%.

The given probabilities for the vowels are:

• A: 11%
• E: 21%
• I: 12%
• O: 6%
• U: 3%

Let's calculate the total probability of selecting a vowel:

$\text{Total vowel probability} = 11\% + 21\% + 12\% + 6\% + 3\% = 53\%$

Now, subtract this from 100% to find the probability of selecting a letter that is not a vowel:

$\text{Probability not a vowel} = 100\% - 53\% = 47\%$

So, the probability that a random letter is not a vowel is 47%.

Tip:

Always double-check that the sum of all probabilities equals 100%, as this ensures all possible outcomes are accounted for.
