What is the formula to calculate the total number of combinations of ice cream with different flavors, toppings, and cones?

Back

Total combinations = (Number of flavors) x (Number of toppings) x (Number of cones).

Front

If an ice cream parlor has 6 flavors, 4 toppings, and 2 types of cones, how many total combinations can be made?

Back

48 combinations.

Front

What is the probability of selecting a red ball from a basket containing 5 red, 3 yellow, and 2 green balls?

Back

Probability = (Number of red balls) / (Total number of balls) = 5/10 = 1/2.

How do you calculate the experimental probability of an event?

Back

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

Front

Front

What is the difference between experimental probability and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes.

Front

In a probability experiment, if a number cube is rolled 60 times, how do you determine which side's experimental probability is closest to its theoretical probability?

Back

Compare the frequency of each side's outcomes to their expected theoretical probabilities.
