We know that Sally received the 25% of votes (i.e 1/4), which means that maya received the remaining 75% (i.e. 3/4) of votes.
So, if there was a total of 125000 votes, Maya received 3/4 of them:
.
In fact, you can check that Sally received
votes, which is indeed one quarter of the total:
Answer:
51-55 1 0
56-60 2 0
61-65 1 0
66–70 2 8
71–75 1 3
76–80 0 4
81–85 0 1

The answer is "c. continuous probability distribution."
"Continuous" means it is a subset of the real numbers set: it can take any value in a specified range. For example, if you break at random a stick with a given length of 12 cm, and then measure the shortest piece, you can get any value in the range (0 cm, 6 cm). This is a continuous random variable.
A random variable is said to be "discrete" if it can only take values from a finite (or countably infinite) set. For example, if you roll a dice, you can get only 1, 2, ..., 6. But you cannot get any vaue in the range [1, 6], because the value must be an integer (e.g., you cannot get the vaue 2.5). This is a discrete random variable.
A somewhat technical explanation:
- A random variable is a mapping from a event space to a number set: it associates a number (a value of the variable) with every event.
- The random variable is said to be continuous if it maps events to numbers from a subset of the set of real numbers.
- The probability distributions corresponding to continuous random variables are called continuous probability distributions.
