What is theoretical probability?

Back

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

Front

How do you calculate experimental probability?

Back

Experimental probability is calculated by dividing the number of times an event occurs by the total number of trials conducted.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points within certain ranges (bins).

Front

What does it mean if a student is selected at random?

Back

Selecting a student at random means that every student has an equal chance of being chosen, ensuring that the selection is unbiased.

Front

If a bag contains 4 balloons of different colors, how do you find the probability of picking a specific color?

Back

To find the probability of picking a specific color, divide the number of that color balloon by the total number of balloons in the bag.

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 results from trials.

Front

How do you interpret data from a histogram?

Back

To interpret data from a histogram, look at the height of the bars to understand the frequency of data points within each range.

Front

What is the probability of flipping a coin and getting heads?

Back

The theoretical probability of flipping heads is 1/2, since there are two possible outcomes: heads or tails.

Front

If a student recorded 7 heads and 3 tails after 10 coin flips, what is the experimental probability of getting heads?

Back

The experimental probability of getting heads is 7/10, since heads occurred 7 times out of 10 flips.

Front

What does it mean if the experimental probability is different from the theoretical probability?

Back

If the experimental probability differs from the theoretical probability, it may indicate that the trials were not sufficient or that random variation occurred.
