PLZ HURRY IT'S URGENT!!

Answer:

OPTION C: 60%

Step-by-step explanation:

Chances of raining the next day + Chances that it will not rain = 100%

One of them should definitely be true.

So, if the chance of it raining tomorrow is 40% then there is 60% chance that it will not rain tomorrow.

This can also seen as follows:

Probability of rain tomorrow + Probability of no rain = 1

Given Probability of rain tomorrow = 40% = $\frac{40}{100} = \frac{2}{5}$

Probability of no rain tomorrow = 1 - Probability of rain tomorrow

⇒ Probability of no rain = 1 - $\frac{2}{5}$

⇒ Probability of no rain = $\frac{3}{5}$

Expressing it as percentage: $\frac{3}{5} \times 100$ = 60%.
