There are 4 broken eggs out of a shipment of 600 eggs. If another shipment has 3,300 eggs, how many would be expected to be broken?

• Expected broken eggs in 3,300 eggs is 22.

• Expected broken eggs in 3,300 eggs is 18.

• Expected broken eggs in 3,300 eggs is 24.

How does experimental probability with theoretical probability?

• The experimental probability is always equal to the theoretical probability.

• The experimental probability is always greater than the theoretical probability.

• The experimental probability may vary and can be equal, greater, or less than the theoretical probability depending on the situation.

A bag contains the letters shown. You randomly draw a tile, record it, and then return it to the bag. The bar graph shows the results of drawing a letter 50 times. Compare the theoretical and experimental probabilities of the event. What is the probability of drawing an S?

The student council randomly selected 25 students in the school to ask them to choose their favorite chips. The results of the random sample survey are in the table.

Based on the survey, what is the experimental probability that the next student that is surveyed will choose Doritos as their favorite chips?
