Theoretical and Experimental Probability

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event happening based on actual experiments or trials, 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 possible outcomes).

Front

What is the probability of rolling a 1 on a 6-sided die?

Back

The probability of rolling a 1 on a 6-sided die is 1/6.

Front

If a die is rolled 90 times and the number 1 appears 13 times, what is the experimental probability of rolling a 1?

Back

The experimental probability of rolling a 1 is 13/90.

Front

How many sides does a standard number cube (die) have?

Back

A standard number cube (die) has 6 sides.

Front

If a coin is tossed 18 times and lands on heads 12 times, how many times did it land on tails?

Back

It landed on tails 6 times.

Front

What is the experimental probability of a coin landing on tails if it landed on heads 12 times out of 18 tosses?

Back

The experimental probability of landing on tails is 6/18, which reduces to 1/3.

Front

What is the formula for calculating experimental probability?

Back

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

Front

If a spinner is spun 200 times and lands on a 3, how do you find the experimental probability of landing on a 3?

Back

Divide the number of times it landed on 3 by 200.
