Can someone give me a formula for this question?
Wanda said there was a 30% chance of rain for both Saturday and Sunday. It rained on both days.
If her calculations were correct and there was a 30% chance of rain each day, what is the probability there would be rain on both days?
Please help!!!

Here is a formula: $P(A\text{ and }B)=P(A)P(B)$ for independent events $A$ and $B$.
