Probability

The video tutorial covers probability concepts using dice and coin examples, explaining how to calculate the probability of specific outcomes. It also introduces 'both or neither' questions, providing a formula to solve them. Two example problems are discussed: one involving restaurant orders and another involving student participation in dance and chorus at a school.

What is the probability of rolling double sixes with two dice?

• 1/36

• 1/6

• 1/18

• 1/12

If you flip a coin three times, what is the probability of getting heads all three times?

• 1/8

• 1/6

• 1/2

• 1/4

In a restaurant with 100 customers, 60 order salad, 35 order soup, and 20 order neither. How many order both?

• 10

• 25

• 15

• 20

What is the formula used to solve 'both or neither' problems?

• G1 + G2 + N = Total

• G1 + G2 - B = Total

• G1 + G2 + N - B = Total

• G1 + G2 - N + B = Total

At a Performing Arts High School, 60% of students take dance, 50% take chorus, and 20% take both. What percentage take neither?

• 10%

• 20%

• 30%

• 40%

How do you solve a probability problem involving multiple events?

• Add the probabilities of each event

• Multiply the probabilities of each event

• Subtract the probabilities of each event

• Divide the probabilities of each event

What is the key step in solving 'both or neither' problems?

• Identifying the total number of items

• Identifying the number in the both category

• Identifying the number in the neither category

• Identifying the number in both and neither categories
