1The [blank_start]event space[blank_end] is the entire set of possibilities in a trial.
- Aevent space
2An event is a [blank_start]specific outcome or set of outcomes[blank_end] that you're interested in during a trial.
- Aspecific outcome or set of outcomes
3A [blank_start]probability measure[blank_end] is the assignment of probabilities to events.
- Aprobability measure
4A probability measure assigns a number between [blank_start]0[blank_end] and [blank_start]1[blank_end] to each event.
- A0
- B1
5A probability of [blank_start]0[blank_end] means the event is impossible.
- A0
6A probability of [blank_start]1[blank_end] means an event is certain.
- A1
7The __________ describes how likely each outcome is within a discrete probability distribution.
- AProbability Mass Function
- BCumulative Mass Function
- CCumulative Distribution Function
8In a [blank_start]discrete probability distribution[blank_end], the probabilities assigned to each possible outcome are non-negative and their sum equals one (1).
- Adiscrete probability distribution
9[blank_start]Factorial notation[blank_end] helps us calculate the number of possible arrangements or permutations of a set of objects.
- AFactorial notation
10In mathematics, combinations represent the number of ways to choose a certain number of objects from a larger set without considering the [blank_start]order in which they are chosen[blank_end].
- Aorder in which they are chosen
11The [blank_start]cumulative mass[blank_end] function tells you the probability of getting an outcome of any outcome below it.
- Acumulative mass
12A [blank_start]binomial distribution[blank_end] is like a mathematical tool we use when we're interested in the number of successes we might get out of a fixed number of attempts or trials.
- Abinomial distribution
13The binomial distribution is used in which of the following situations?
- AA random process is taking place, consisting of a series of trials.
- BOn each trial, one of two events could happen.
- CThe probability of success on each trial is a fixed constant.
- DEach trial is independent of the others, meaning the outcome of one trial doesn't affect the outcome of the next.
14What is the name of this formula and when is it used?
- Abinomial probability formula
