Final answer:

The chance that it will rain on both Monday and Tuesday based on a 60% chance on Monday and a 30% chance on Tuesday is found by multiplying the probabilities, resulting in an 18% chance of rain on both days.

Step-by-step explanation:

To calculate the chance it will rain on both Monday and Tuesday, you multiply the probabilities of each event happening independently.

The chance that it will rain on both Monday and Tuesday based on a 60% chance on Monday and a 30% chance on Tuesday is found by multiplying the probabilities, resulting in an 18% chance of rain on both days. The probability of rain on Monday is 60%, or 0.60, and the probability of rain on Tuesday is 30%, or 0.30.

The chance it will rain on both days is the product of the two probabilities: 0.60 (Monday's probability of rain) × 0.30 (Tuesday's probability of rain) = 0.18 or 18%.

Therefore, based on the weather report, the chance that it will rain on both Monday and Tuesday is 18%, which corresponds to option B.
