There are 365 days in a year. If it is a leap-year, then there are 366 days.
Rainy days are not independent events, but for theis question you will need to assume that they are. Otherwise, there is insufficient information to answer. Prob(a day being rainy) = 0.1 so Prob(a day being not rainy) = 1 - Prob(a day being rainy) = 1 - 0.1 = 0.9 Therefore, Prob(7 days being no rainy) = (0.9)7 and so, Prob(At least one rainy day in 7) = 1 - Prob(no rainy days in 7) = 1 - (0.9)7 = 0.5217 (approx).
There are 365 days in a year.
