Answer: 1/45
Explanation:
The probability that it will rain this week and then rain next week will be the multiplication of the both the probability that it'll rain this week and probability that it'll rain next week.
Therefore, the answer will be:
= P(rain this week) × P(rain next week)
= 1/9 × 1/5
= 1/45
Therefore, the answer is 1/45.
