What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted.

How do you calculate the experimental probability of selecting a red jelly bean from a bag containing 5 green, 2 red, and 3 blue jelly beans?

Back

The experimental probability of selecting a red jelly bean is calculated as the number of red jelly beans divided by the total number of jelly beans: 2/(5+2+3) = 2/10 = 1/5.

Front

What is theoretical probability?

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a given situation.

Front

How do you calculate the theoretical probability of pulling a red marble from a bag containing 4 green, 3 red, 2 blue, and 1 yellow marble?

Back

The theoretical probability of pulling a red marble is calculated as the number of red marbles divided by the total number of marbles: 3/(4+3+2+1) = 3/10.

Front

What is a sample space in probability?

Back

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

Front

What is the sample space for flipping two coins?

Back

The sample space for flipping two coins is: HH, HT, TH, TT.

Front

How do you calculate the probability of selecting a brown M&M from a bowl containing 4 yellow, 6 orange, 3 green, 5 blue, and 2 brown M&Ms?

Back

The probability of selecting a brown M&M is calculated as the number of brown M&Ms divided by the total number of M&Ms: 2/(4+6+3+5+2) = 2/20 = 1/10.

Front

What is the formula for calculating probability?

Back

The formula for calculating probability is: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments and observations, while theoretical probability is based on mathematical calculations and assumptions.

Front

If a bag contains 10 jelly beans (5 green, 2 red, 3 blue), what is the probability of selecting a green jelly bean?

Back

The probability of selecting a green jelly bean is 5/10 = 1/2.
