Theoretical and Experimental Probability

Front

What is the number of sides on a normal number cube?

Back

6

Front

What is experimental probability?

Back

The probability based on the actual results of an experiment.

Front

What is the theoretical probability of rolling a specific number on a number cube?

Back

1/6, since there are 6 equally likely outcomes.

Front

If a number cube is rolled 50 times and the number 1 appears 10 times, what is the experimental probability of rolling a 1?

Back

10/50 or 1/5.

Front

What is the formula for calculating experimental probability?

Back

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

Front

What is the theoretical probability of rolling an even number on a number cube?

Back

3/6 or 1/2, since there are 3 even numbers (2, 4, 6) out of 6.

Front

How many times was the number cube rolled in the given bar graph?

Back

50 times.

Front

If Neil tossed a 6-sided die 90 times and rolled a 1, which had an experimental probability of 13/90, how many times did he roll a 1?

Back

13 times.

Front

What is the difference between theoretical and experimental probability?

Back

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

Front

What is the probability of rolling a number greater than 4 on a number cube?

Back

2/6 or 1/3, since the numbers greater than 4 are 5 and 6.
