Exploring Simple and Compound Probability

The video tutorial covers the basics of probability, including simple and compound probability, and explains how to calculate probabilities using examples with chips and marbles. It discusses the concept of dependent events and the difference between replacement and non-replacement scenarios. The tutorial provides step-by-step calculations and highlights the importance of understanding these concepts in probability.

What is the probability of drawing a red chip from a bowl containing various colored chips?

• 1/5

• 3/15

• 2/10

• 1/2

How can probability be expressed?

• Only as a percentage

• Only as a decimal

• Only as a fraction

• As a fraction, a decimal, or a percentage

What defines dependent events in probability?

• Events where the outcome of one affects the outcome of the other

• Events where the outcome of one does not affect the other

• Events that can occur independently

• Events that have the same probability of occurring

What is the probability of drawing a red marble and then a green marble with replacement?

• 4/45

• 5/15

• 1/3

• 4/15

What does 'with replacement' mean in the context of drawing marbles from a bag?

• Not allowing the marble to be drawn again

• Putting the marble back after drawing

• Drawing two marbles at the same time

• Keeping the marble aside after drawing

What is the probability of drawing a red marble and then a green marble without replacement?

• 20/210

• 2/21

• 4/45

• 1/3

How does not replacing a marble after drawing it affect the probability of subsequent draws?

• Increases the total number of outcomes

• Decreases the total number of outcomes

• Changes the color of the marbles

• Does not affect the total number of outcomes

What is the probability of drawing a blue chip, then an orange chip, with replacement from a bin?

• 2/16

• 1/8

• 1/16

• 1/2

What is the probability of drawing a green chip, then an orange chip, then a green chip again without replacement?

• 2/15

• 3/8

• 30/1680

• 1/56

What does the probability of 2 out of 21 signify in the context of drawing a red marble followed by a green marble without replacement?

• It will never happen

• It signifies the total number of marbles

• It will happen 2 out of every 21 attempts on average

• It will happen every time
