Question

read the story.
seth adopts 4 baby chickens. there is a 50% chance that each will be a hen. how likely is it that all 4 baby chickens will be hens?
which simulation could be used to fairly represent the situation?
create a spinner with 5 equal sections. color 2 sections yellow and 3 sections green. spin the spinner 4 times. each time the spinner lands on a yellow section, it represents a hen.
put 4 blue marbles and 4 red marbles in a bag. draw a marble from the bag, and then return it to the bag, 8 times. each time a blue marble appears, it represents a hen.
create a deck of 50 cards, each with a different number from 1 to 50. pick a card from the deck, and then return it to the deck, 4 times. each time an even number appears, it represents a hen.

Explanation:

Step1: Analyze the first option

A spinner with 5 equal sections, 2 yellow and 3 green. The probability of yellow (hen) is $\frac{2}{5} = 40\%$, not 50%. So this is incorrect.

Step2: Analyze the second option

A bag with 4 blue and 4 red marbles. The probability of blue (hen) is $\frac{4}{8} = 50\%$, but we need to draw 4 times (for 4 chickens), not 8. So this is incorrect.

Step3: Analyze the third option

A deck of 50 cards (1 - 50). The number of even numbers is 25, so the probability of even (hen) is $\frac{25}{50} = 50\%$. We pick 4 times (for 4 chickens), which matches the situation. So this is correct.

Answer:

Create a deck of 50 cards, each with a different number from 1 to 50. Pick a card from the deck, and then return it to the deck, 4 times. Each time an even number appears, it represents a hen.
