Experimental Sample and Probability

Rylee is on a weekend fishing trip with her family. So far she has caught 4 trout, 10 catfish, and 13 bluegill. What is the probability that the next fish that Rylee catches will be a catfish?

• 37%

• 15%

• 48%

• 38%

The extent to which something is likely to occur is known as - 

• sample space

• an event

• probability

• data

The likelihood that a single, specific event will occur is called - 

• sample space

• compound probability

• a complement

• simple probability

The ratio of the number of times an event occurred compared to the total number of trials conducted is known as - 

• theoretical probability

• experimental probability

• simple probability

• compound probability

A set of all possible outcomes is known as - 

• list

• complement

• sample space

• event

How do we determine which event is most likely to occur?

• The event has the closest improper fraction to 1

• The event has the closest proper fraction to 1/2

• The event has the closest proper fraction to 0

• The event has the closest proper fraction to 1

In probability theory, the sum of an event (A) occurring and the same event NOT occurring (not A) is always - 

• 0

• based on the sample space

• variable

• 1

Which of the following expressions would be used to calculate the complement of an event occurring?

• P(event) - 1

• P(event 1) x    P(event 2)

• P(event)/possible outcomes

• 1 - P(event)

Which of the following expressions can be used to calculate the probability of two related events occurring?

• P(event) x 2

• P(event 1) +   P(event 2)

• P(event 1) x     P(event 2)

• P(event 1 + 2)

The likelihood that an event will NOT occur is known as its - 

• complement

• sample space

• opposite

• trial
