Probability

What is the sample space in a random experiment?

• The set of all possible outcomes

• The actual outcome of the experiment

• The subset of possible outcomes

• The probability of an event

How is the probability of an event calculated?

• By dividing the number of favorable outcomes by the total number of possible outcomes

• By counting the number of times the event occurs

• By comparing it to another event

• By estimating the likelihood of the event

In theoretical probability, what is the probability of drawing a green marble from a box containing 1 yellow, 2 green, 3 red, and 4 blue marbles?

• 4/10

• 3/10

• 2/10

• 1/10

What distinguishes experimental probability from theoretical probability?

• It is based on actual outcomes rather than expected outcomes

• It uses a formula to calculate probabilities

• It is always more accurate

• It does not require any experiments

If 5 out of 30 marbles drawn are yellow, what is the experimental probability of drawing a yellow marble?

• 1/3

• 1/6

• 1/5

• 1/10
