Quiz Answer Key and Fun Facts

1. What is the general formula for the factorial notation?

Answer: n*(n-1)*(n-2)*...*3*2*1

Factorial notation is generally represented by n! and involves consecutive numbers multiplied together in descending order until the number reaches one.

2. How can C(n,r) be represented in factorial form?

Answer: n! over (n-r)!r!

A combination is a choice of a number of elements from a given set without regard to order.

3. How many different masses can be obtained using weights of mass 1kg, 2kg, 5kg, and 10kg?

Answer: 15

Number of possible weightings would be 2 to the power of 4 and then subtracted one because the case with no weightings taken is discounted.

4. What is the probability of throwing a sum of 7 on two dice?

Answer: 1 over 6

there are 6 combinations that would make a sum of 7: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1). The total number of combinations is 36. Therefore the probability is 6 over 36 or 1 over 6.

5. Given that the probability of an event A is 9 over 13, what are odds in favour of A?

Answer: 9:4

6. In an ordered set of data, what is the value in the very middle called?

Answer: Median

Mode is the most common value in the data. Average and mean are sum of data divided by the number of data points.

7. Which of the following is NOT a measure of dispersion?

Answer: Weighted mean

8. What does the Normal Distribution Graph look like?

Answer: Bell-Shaped

Normal Distribution graph is bell-shaped showing the proportion of observations within one, two, or three standard deviations from the mean.

9. In how many ways can four people be seated around a circular table?

Answer: 6

Using one person as a 'marker', find the factorial of the rest: 3!=6

10. What is the symbol used to represent summation notation called?

Answer: Sigma
