Question

the forecast calls for a 30% chance of snow today and a 40% chance of snow tomorrow. what are the chances it will rain two days in a row?

Answer 1

The chances it will rain two days in a row is 12%

Explanation:

The forecast calls for a 30% chance of snow today

So, chance of snowfall today = 30% = 0.3

A 40% chance of snow tomorrow.

So, chance of snowfall tomorrow= 40% = 0.4

The chances it will rain two days in a row =
`0.4  * 0.3`

=
`0.12`

So, percent it will rain two days in a row =
`0.12 * 100 = 12\%`

Hence the chances it will rain two days in a row is 12%
