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

Answer:

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

Step-by-step 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 = $0.4 \times 0.3$

                                                                    = $0.12$  

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

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