Question

PLZ HURRY IT'S URGENT!!

f the chance of rain for tomorrow is 40%, what is the chance that it will NOT rain?
Note: You can choose more than one answer.

40%

10%

60%

100%

Answer 1

OPTION C: 60%

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% =
`$ (40)/(100) = (2)/(5) $`

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

⇒ Probability of no rain = 1 -
`$ (2)/(5) $`

⇒ Probability of no rain =
`$ (3)/(5) $`

Expressing it as percentage:
`$ (3)/(5) * 100 $` = 60%.
