Answer:
In this case Jack is only using a part or sample of the total population, so he is doing a sample standard deviation. When you use the total population you are doing a population standard deviation, otherwise, it’s always going to be the sample standard deviation.
Both deviations have different notations. The notation for this type of standard deviation (the one used by Jack) is:
"n" for the number of observations (lowercase)
"x-bar" for the average of the sample
"s" for the standard deviation
"s^2" for the variance

Step-by-step explanation:
<u>Probability of getting heads</u>
- Outcome (head) = 1
- Total outcomes = 2
- P (head) = <u>1/2</u>
<u></u>
<u>Probability of getting an odd number</u>
- Outcome (odd) = {1, 3, 5} = 3
- Total outcomes = 6
- P (odd) = 3/6 = <u>1/2</u>
<u></u>
The outcomes are equally likely because the probabiity of each outcome is the same.
