$\frac{2}{73}$ $2/73$

Explanation:

P(birthday on a wet June day)
= $\frac{10}{365}$ $10/365$
= $\frac{2}{73}$ $2/73$

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