Relative Frequency and Probability Concepts

The video tutorial covers module 10 lesson two on relative frequency of simple events. It includes various examples such as basketball free throws, dart tossing, and marble drawing to explain the concept of probability and relative frequency. Definitions and calculations are provided to help understand how to determine the likelihood of events occurring. The lesson also includes practical examples like a zoo exhibit survey and golf scores to illustrate the application of relative frequency in real-world scenarios.

What is the main focus of module 10 lesson two?

• Learning about relative frequency of simple events

• Studying historical events

• Understanding algebraic expressions

• Exploring geometric shapes

In the basketball example, what is the expected number of successful free throws out of 500 attempts if the success rate is 90%?

• 350

• 500

• 450

• 400

What is the probability of hitting the target in the dart experiment if 28 out of 100 darts hit the target?

• 0.18

• 0.28

• 0.48

• 0.38

How does reducing the target size in the dart experiment affect the probability of hitting it?

• Increases the probability

• Doubles the probability

• Decreases the probability

• Has no effect

What is a simple event in probability?

• An event with infinite outcomes

• An event with no outcomes

• An event with a single outcome

• An event with multiple outcomes

In the strawberry star example, what is the relative frequency of getting a strawberry star if 36 out of 80 stars are strawberry?

• 0.55

• 0.36

• 0.25

• 0.45

What is the relative frequency of rolling a five on a number cube if it occurs 4 times out of 20 rolls?

• 0.20

• 0.25

• 0.15

• 0.30

In the marble exercise, what is the relative frequency of drawing a yellow marble if it is drawn 10 times out of 50?

• 0.10

• 0.20

• 0.30

• 0.40

In the zoo survey example, what is the relative frequency of the favorite exhibit being either Penguins or Bears if 19 out of 70 students chose them?

• 0.57

• 0.37

• 0.27

• 0.47

In the golf scores exercise, what is the relative frequency of scoring a four or a five if these scores occur 18 times out of 30?

• 0.80

• 0.50

• 0.60

• 0.70
