Math 7 (Theoretical Probability)

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on the possible outcomes in a perfect scenario, calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.

Front

How do you calculate the theoretical probability of an event?

Back

Theoretical probability is calculated using the formula: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

What is the theoretical probability of not drawing a green ball from a bag containing 1 green and 3 other colored balls?

Back

The theoretical probability of not drawing a green ball is 3/4.

Front

What is the theoretical probability of drawing either a green or red ball from a bag containing 2 green, 1 red, and 2 other colored balls?

Back

The theoretical probability of drawing either a green or red ball is 2/5.

Front

What is the theoretical probability of rolling an odd number on a standard six-sided die?

Back

The theoretical probability of rolling an odd number (1, 3, or 5) is 3/6 or 1/2, but if the question refers to a different context, it could be 7/10 based on specific conditions.

Front

What is the theoretical probability of randomly selecting a boy from a group of 8 students, 3 of whom are boys?

Back

The theoretical probability of selecting a boy is 3/8.

Front

What is the theoretical probability of rolling a number 2 or higher on a standard six-sided die?

Back

The theoretical probability of rolling a number 2 or higher is 5/6.

Front

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on the expected outcomes in a perfect scenario, while experimental probability is based on actual results from experiments or trials.

Front

What are favorable outcomes in probability?

Back

Favorable outcomes are the specific outcomes that satisfy the condition of the event for which the probability is being calculated.

Front

What is the total number of outcomes when rolling a six-sided die?

Back

The total number of outcomes when rolling a six-sided die is 6.
