Experimental Probability Test

Front

What is experimental probability?

Back

Experimental probability is the probability of an event based on the results of an experiment or observation, calculated as the number of times the event occurs divided by the total number of trials.

Front

How do you calculate the probability of an event?

Back

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

Front

What is the theoretical probability of an event?

Back

Theoretical probability is the probability of an event based on the possible outcomes in a perfect scenario, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

If a spinner has 8 equal sections numbered 1 to 8, what is the probability of landing on a number less than 6?

Back

P(number < 6) = 5/8 or 62.5%.

Front

What is the probability of rolling a 5 on a 6-sided die?

Back

P(rolling a 5) = 1/6.

Front

In a bag with 5 green, 2 red, and 3 blue jelly beans, what is the probability of selecting a red jelly bean?

Back

P(selecting red) = 2/10 or 1/5.

Front

What is the probability of rolling greater than a 1 on a single die?

Back

P(rolling > 1) = 5/6.

Front

What does it mean to reduce a fraction in probability?

Back

Reducing a fraction means simplifying it to its lowest terms by dividing the numerator and denominator by their greatest common divisor.

Front

If you have a probability of 4/9 for an event, what does this mean?

Back

It means that out of 9 trials, you can expect the event to occur 4 times.

Front

What is the total number of outcomes when tossing a 6-sided die?

Back

The total number of outcomes is 6.
