Probability and Spinner Game Concepts

Mrs. Zapia's lesson on estimating probabilities involves understanding probability concepts, playing a game to collect data, and analyzing results to estimate probabilities. Students learn to express probabilities as fractions and apply these skills to different scenarios, such as a game with a spinner and selecting animal crackers. The lesson emphasizes the importance of data collection and analysis in estimating probabilities.

What is the main focus of this lesson on estimating probabilities?

• Learning about different types of data

• Estimating probabilities by collecting data

• Understanding the concept of probability

• Playing games to win prizes

In the spinner game, what is the condition for winning a prize?

• The sum of spins is less than five

• The sum of spins is greater than or equal to five

• The sum of spins is an even number

• The sum of spins is exactly five

How many times did the sum of the spins result in a number greater than or equal to five?

• Eight times

• Five times

• Twelve times

• Ten times

Which sum was impossible to achieve in the spinner game?

• Nine

• Seven

• Five

• Two

What is the probability of getting a sum of five or more in the spinner game?

• 4/15

• 8/15

• 10/15

• 12/15

How is the probability of an event expressed in terms of fractions?

• Numerator is total observations, denominator is occurrences

• Numerator is occurrences, denominator is total observations

• Both numerator and denominator are occurrences

• Both numerator and denominator are total observations

In the animal crackers experiment, what is the probability of selecting a lion?

• 1/20

• 1/10

• 1/4

• 1/5

What is the probability of selecting a rabbit from the jar?

• 1/5

• 1/20

• 0

• 1/10

If 500 animal crackers are in the jar, how many are expected to be elephants?

• 100

• 125

• 200

• 150

Why might the results differ if another 20 animal crackers are selected?

• The jar is empty

• The selection process is random

• The crackers are all the same

• The jar has been replaced
