# There were 10 wet days in June last year. If the name of an individual is selected at random from a directory, write down the probability that his or her birthday last year was on a wet June day. Assume all birthdays are equally liked?

$\frac{2}{73}$
= $\frac{10}{365}$
= $\frac{2}{73}$
There are 365 days in a year. So the probability of a person's birthday falling on a day is $\frac{1}{365}$. Since there are 10 wet days, the probability of a person's birthday falling on the wet days is $10 \times \frac{1}{365}$
