Suppose R and Q are two events such that P(R)= .14, P(Q) = .52, and P(R∩Q)= .20, find P(RUQ), are the events mutually exclusive why or why not?

Answers

Answer 1

Answer:

#

P(R I Q) = P(RnQ) / P(Q) = 0.1 Therefore P(RnQ) = 0.1 X 0.35 = 0.035 (The intersection in the centre of a Venn Diagram)

P(RnQ') = 0.15 In a Venn Diagram this is R but excluding the centre intersection with Q. Therefore P(R) = P(RnQ') + P(RnQ) = 0.15 + 0.035 = 0.185

P(RUQ) = 0.15 + 0.035 + 0.315 = 0.5 so 0.5 must be outside the Venn Diagram circles.

Answer:

A, the previous answerer is correct.

Explanation:

I just took the quiz, answered A on this question, and got a 100%. (On Edge 2021, AP Environmental Science). None of the other answers could cause a greenhouse effect, which is what they want to make sure you understand. The clouds in the troposphere keep some of the outbound UV radiation (after the Earth's surface reflects it) from leaving the Earth, which is why it keeps the Earth warmer.

Global climate change occurs because of increasing concentrations of greenhouse gases in; Option A; the troposphere, which absorbs outgoing IR radiation

The part of the atmosphere in which greenhouses are found is the Troposphere.

Now, Greenhouse gases are a set of gases that accumulate in the lower layer of the atmosphere, which is called the Troposphere.

Now this lower layer of the atmosphere usually absorbs infrared radiation and this contributes to increasing the average temperature of the surface of the earth.

Looking at the given options, the correct one in relation the greenhouse gases is option A.
