Question

Qus.13/ In a certain city out of 30 days of a month it rains on 8 days find the probability
given day selected it does not rain.​

Answer 1

Answer:

P(of not raining) = 11/15

Step-by-step explanation:

We know that,

Probability = Possible outcomes/Total outcomes

P(of raining) = 8/30

= 4/15

We know that,

P(of raining) + P(of not raining) = 1

Thus,

P(of not raining) = 1 - P(of raining)

P(of not raining) = 1 - (4/15)

P(of not raining) = (15/15) - (4/15)

P(of not raining) = 11/15

OR

Now, In a month of 30 days, it rains 8 days.

Thus,

(30 - 8) days it doesn't rain

= 22 days it doesn't rain

Hence,

P(of not raining) = 22/30

P(of not raining) = 11/15
