Answers

We are given
Revenue, g(x) = 2300x+1235, and
expenses, f(x) = 1600x+2385

We know that
profit = Revenue - expenses
=g(x)-f(x)
=2300x+1235 - (1600x+2385)
=2300x+1235 - 1600x - 2385
=2300x- 1600x +1235 -2385
=700x - 1150

If there is an 80% chance of rain and a 50% chance of wind and rain, what is the probability that it is windy, given that it is rainy? Round your answer to the nearest percent.

Answers

Answer:

The probability that it is windy, given that it is rainy is:

                             62.5%≈63%

Step-by-step explanation:

Let A denote the event that it will rain.

B denote the event that it is windy.

A∩B denote the event that it is rainy and windy.

Let P denote the probability of an event.

i.e. we have:

P(A)=0.80

( Since there are 80% chance of rain)

P(A∩B)=0.50

(Since there are 50% chance of wind and rain)

We are asked to find:

P(B|A)

We know that:

P(B|A)=(P(A\bigcap B))/(P(A))\n\n\nP(B|A)=(0.50)/(0.80)\n\n\nP(B|A)=0.625

Hence, the probability in percent is:

                   62.5%≈63%

The total probability when given it is rainy is 80%. Among them, the windy probability among 80% is 50%. So the total probability is 50%/80%=62.5%≈63%.
