Given that there is a 23% chance it will rain on any day, what is the probability that it will rain on the first day and be clear (not rain ) on the next two days?

Respuesta :

Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .

Step-by-step explanation:

We are given that there is a 23% chance it will rain on any day, we need to find  what is the probability that it will rain on the first day and be clear (not rain ) on the next two days . Let's do it step by step:

Probability for first day is to rain i.e. [tex]\frac{23}{100} = 0.23[/tex].

Probability for second day is to not rain i.e. [tex]1-\frac{23}{100} =1- 0.23=0 .77[/tex].

Probability for third day is to not rain i.e. [tex]1-\frac{23}{100} =1- 0.23=0 .77[/tex].

Now, Probability for occurrence of these 3 events simultaneously is :

⇒ [tex](0.23)(0.77)(0.77)[/tex]

⇒ [tex](0.23)(0.5929)[/tex]

⇒ [tex]0.1719[/tex]

Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .
