Answer
N = 32 ÷ (5 - 1)
N = 32 ÷ 4
N =8
Step-by-step explanation:
We are asked to find the probability that the student sold 11-15 T-shirts or less than 6 T-shirts.
The total number of club members = 2 + 14 + 12 + 3 + 6 + 1 = 38
Probability of 11-15 T-shirts:
From the table, 3 club members bought 11 - 15 T-shirts.
So the probability is 3/38
Probability of less than 6 T-shirts:
Less than 6 T-shirts means 1 - 5 plus 0 T-shirts.
Form the table, 14 club members bought 1 - 5 T-shirts and 2 club members bought 0 T-shirts.
Total club member who bought 1 - 5 and 0 T-shirts = 14 + 2 = 16
So the probability is 16/38
Now we have to add them together to find the probability that the student sold 11-15 T-shirts or less than 6 T-shirts.
(or means to add)
So the probability is 3/38 + 16/38 = 19/38 = 0.5000
Therefore, the correct answer is option c.

1) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum simple interest after 6 years are <u>R25,400</u> and <u>R5,400</u> respectively.
2) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum compound interest after 6 years are<u> R26,045.20</u> and <u>R6,045.20</u> respectively.
<h3>Data and Calculations:</h3><h3>Simple Interest:</h3>
Principal = R20,000
Investment period = 6 years
Interest rate = 4.5%
Simple interest for 6 years = R5,400 ($20,000 x 6 x 4.5%)
Principal + Interest = R25,400 (R20,000 + R5,400)
<h3>Compound Interest:</h3>
Principal = R20,000
Investment period = 6 years
Interest rate = 4.5%
N (# of periods) = 6 years
I/Y (Interest per year) = 4.5%
PV (Present Value) = R20,000
PMT (Periodic Payment) = R0
<u>Results</u>:
FV = R26,045.20
Total Interest = R6,045.2
