Question 2 (1 point)
Cards numbered 1 through 15 are mixed up and placed in a bag. Malik chooses one of the cards without looking.

What is the probability that Malik chooses a card with a number greater than or equal to 12?

A box is filled with black (B), white (W), red (R), green (G), and pink (P) phone cases. A phone case is selected at random.

What is the sample space for this experiment?

Let's address each question one by one.

Question 1

For the spinner question, since I cannot see the spinner image you're referring to, I can provide the general answer method.

  1. Count the total number of sections on the spinner.
  2. Count the number of sections that represent the number "2".
  3. Calculate the probability using the formula: \[ \text{Probability of spinning a 2} = \frac{\text{Number of sections with 2}}{\text{Total number of sections}} \]

If the spinner has sections labeled and you can provide that information, I can assist further.

Question 2

Malik has cards numbered from 1 to 15. To find the probability of choosing a card with a number greater than or equal to 12:

  1. Identify the favorable outcomes: The numbers 12, 13, 14, and 15 are greater than or equal to 12. There are 4 favorable outcomes.
  2. Count the total outcomes: There are 15 total cards numbered from 1 to 15.
  3. Calculate the probability using the formula: \[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total outcomes}} = \frac{4}{15} \]

Question 3

To determine the sample space for the experiment of selecting a random phone case from a box filled with cases of various colors:

  1. List all possible outcomes (the types of cases you have): Black (B), White (W), Red (R), Green (G), and Pink (P).
  2. The sample space (S) will include all possible selections, so it should include all listed colors.

Thus, the correct answer is: \[ S = {B, W, R, G, P} \]

It seems that option is not directly listed in the provided choices. If you need to select from the given options, it would be helpful to clarify that kind of representation.
