In a survey of 100 people, some of them jog for exercise, some of them ride a bike, some do both, and 15 do not jog or ride a bi
masya89 [10]

Answer:

Bike alone = 39

Step-by-step explanation:

Given that:

Total number = n(T) = 100

Jog= n(J)

Bike = n(B)

Bike and jog = n(BnJ) = 21

Number who jog = 46

Jog alone = 46 - 21 = 25

Neither jog nor bike = 15

Let bike alone = x

Hence,

Jog alone + bike alone + jog and bike + none of the two = 100

25 + x + 21 + 15 = 100

x = 39

Project B is preferable solely from the standpoint of expected monetary return.

Step-by-step explanation:

Calculations of Expected Returns:

Project A:

Net Profits             Probability          Expected Returns:

GHȼ 20,000.00    0.2                      GHȼ 4,000

GHȼ 30,000.00    0.4                      GHȼ 12,000

GHȼ 50,000.00    0.4                      GHȼ 20,000

Total Expected Returns                   GHȼ 36,000

Project B:

Net Profits             Probability          Expected Returns:

GHȼ 100,000         0.5                      GHȼ 50,000

GHȼ 0.00               0.5                      GHȼ 0.00

Total Expected Returns                   GHȼ 50,000

Expected Returns are the returns or income which have been weighed with their probabilities of occurrence.  It is used to determine the best outcome given events that have different probabilities of occurring.   It is an important measure of returns which helps in deciding the best investment option to pursue.
