You recently purchased a stock that is expected to earn 12.6 percent in a booming economy, 8.9 percent in a normal economy and lose 5.2 percent in a recessionary economy. Each economic state is equally likely to occur. What is your expected rate of return on this stock?

r(e) = 0.05433 or 5.433% rounded off to 5.43%

Explanation:

To calculate the expected rate of return of a stock, we take the rate of return under each scenario and multiply it with the probability of that scenario and sum up the answers for each scenario. The formula for expected rate of return can be written as follows,

r(e) = pA * rA  + pB * rB  +  ...  +  pN * rN

Where,

As we have 3 scenarios with equal probability for each scenario, we can say the probability of each scenario is 1/3.

r(e) =  1/3 * 0.126  +  1/3 * 0.089  +  1/3 * -0.052

r(e) = 0.05433 or 5.433% rounded off to 5.43%

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
