CC1 Chapter 4 Review (24-25)

Front

What is the formula for calculating the probability of an event?

Back

P(Event) = (Number of favorable outcomes) / (Total number of outcomes)

Front

If the probability of picking an orange is 1/3 and the probability of picking an apple is 3/8, how do you calculate the probability of picking either fruit?

Back

P(Orange or Apple) = P(Orange) + P(Apple) - P(Orange and Apple) = 1/3 + 3/8 = 17/24.

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 outcomes.

Front

How do you convert a fraction to a percentage?

Back

To convert a fraction to a percentage, divide the numerator by the denominator and then multiply by 100.

Front

What is the probability of selecting a circle from a bag containing 12 shapes, 5 of which are circles?

Back

P(Circle) = Number of circles / Total shapes = 5/12.

Front

What does it mean if a portion is shaded in a diagram?

Back

It indicates the part of the whole that is covered or filled in, often represented as a fraction or decimal.

Front

How do you express 2/5 as a decimal?

Back

2/5 = 0.4.

Front

What is the decimal equivalent of 0.24?

Back

0.24 is already in decimal form.

Front

What is the probability of an event that has a 24% chance of occurring?

Back

P(Event) = 0.24.

Front

How do you find the total probability of multiple events?

Back

Add the probabilities of the individual events, ensuring to subtract the probability of any overlapping events.
