Math 10.3A: Experimental Probability of Simple Events

Front

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.

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of times the event occurs) / (Total number of trials)

Front

What is the experimental probability of landing on Red if it occurs 12 times out of 50 trials?

Back

12/50 or 6/25

Front

What is the experimental probability of landing on White if it occurs 25 times out of 100 trials, expressed as a decimal?

Back

0.25

Front

What is the experimental probability of landing on Green if it occurs 8 times out of 50 trials?

Back

8/50 or 4/25

Front

If a spinner is divided into 4 equal sections and lands on section C 25 times out of 100 spins, what is the experimental probability of landing on section C?

Back

1/4

Front

In a standard deck of 52 playing cards, what is the probability of drawing a Jack?

Back

1/13

Front

What is the total number of outcomes when rolling a six-sided die?

Back

6 (the outcomes are 1, 2, 3, 4, 5, 6)

Front

If an event has a probability of 0.5, what does this mean?

Back

It means the event is equally likely to occur or not occur.

Front

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from experiments.
