Simple Probability and Complement

Front

What is the sample space in probability?

Back

The sample space is the set of all possible outcomes of a probability experiment.

Front

List the possible combinations of sandwiches (T, C, P) and drinks (M, W).

Back

TW, TM, CW, CM, PW, PM.

Front

What is the probability of choosing a letter other than 'A' from the word 'ALGEBRA'?

Back

5/7.

Front

How do you calculate the probability of an event not occurring?

Back

P(not A) = 1 - P(A).

Front

If a bag contains 4 red, 5 blue, 3 yellow, and 3 green markers, what is the probability of NOT pulling out a blue marker?

Back

2/3.

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of outcomes).

Front

Define 'complement' in probability.

Back

The complement of an event A is the set of all outcomes in the sample space that are not in A.

Front

If P(A) = 1/4, what is P(not A)?

Back

P(not A) = 1 - P(A) = 3/4.

Front

What is the probability of drawing a green marble if there are 5 green marbles out of 19 total marbles?

Back

5/19.

Front

How many total outcomes are there if you have 3 types of sandwiches and 2 types of drinks?

Back

Total outcomes = 3 sandwiches * 2 drinks = 6 outcomes.
