Final answer:
The student's question is about finding the probability of selecting each type of party favor from a box. The probabilities are obtained by dividing the number of each favor by the total number of items.
Step-by-step explanation:
The student's question involves calculating probabilities for selecting different items from a box containing party favors. To find these probabilities, we must know the total number of items in the box and the number of each specific type of favor. The contents of the box include 12 hats, 15 noisemakers, 10 finger traps, and 5 bags of confetti, which totals to 42 items.
Probability Calculations
- To find the probability of getting a hat, P(H), we take the number of hats and divide by the total number of items: 12/42 or about 28.57%.
- The probability of getting a noisemaker, P(N), is 15/42 or approximately 35.71%.
- For a finger trap, P(F), the probability is 10/42 or about 23.81%.
- Last, the probability of getting a bag of confetti, P(C), is 5/42 or roughly 11.90%.
