1/3 of the townspeople have received the full COVID vaccine. 1/3 are immune because they already recovered from COVID. If 1/6 of the townspeople are both vaccinated and already had COVID, what percent of the town is immune in some way?
Use reasoning to answer the following question.
50
First add the fractions of vaccinated and recovered townspeople: 1 / 3 + 1 / 3 = 2 / 3.

Then you need to subtract the fraction that are both vaccinated and recovered, since they were double - counted.

To do this, start by converting 2 / 3 to the same denominator as 1 / 6: 2 / 3 * 2 / 2 = 4 / 6.

Then subtract 1 / 6 from 4 / 6: 4 / 6 - 1 / 6 = 3 / 6.

Then divide the numerator by the denominator and multiply by 100% to express the answer as a percentage: 3 / 6 * 100% = 50%.

.

Therefore, the answer is 50
