Answer:

Option A - Yes this probability model is valid.

Step-by-step explanation:

Given : Sherwin manages Delaroy County Zoo. The following table shows a probability model for the number of visitors on a weekday.

To find : Is this a valid probability model?

Solution :

Probability Model

Number of visitors Probability

         0-49                   0.12

         50-99                      0.26

        100-149                    0.32

        150-199                    0.21

           200+                    0.09

The property of probability is total sum of the probability of an event is always 1.

So, we find the sum of the probability,

i.e. P=0.12+0.26+0.32+0.21+0.09=1

It satisfy the property.

Therefore, Option A - Yes this probability model is valid.

-BARSIC- [3]

Answer:

It is 6%

Explanation:

The stock that is bought by Rick Mendez: 5,000

Own money used to buy: 2,500

Borrowed money: 2,500

Interest on borrowed money : 30

Brokerage commissions: 300

The stock is sold after one month: 5,650

Now first calculate the net profit = Selling price of stock – cost price of stock – Interest on borrowing – commission

5,650-5,000-30-300=320

Now calculate the rate of return = Net profit / cost of stock

320/5,000=.06

.06 or 6%
