In 1900, half of the babies born in America were born with blue eyes. Which simulation could be used to find the probability that 3 out of 4 babies born had blue eyes?

A.
Rolling a 6-sided number cube 3 times

B.
Spinning a spinner with 3 equal sections 4 times

C.
Flipping a coin 4 times

D.
Pick a card from 10 cards 2 times

i think its C but im not sure

yes,

the prob(blue eyes) = 1/2
prob(heads on coin flip) = 1/2

4 babies<---> 4 coin flips

"what is the probability of getting head in 3 out of 4 coin flips" would be the same question.

D. Pick a card from 10 cards 2 times.

Because, you know, babies are always playing with cards. They're practically born card sharks.

To find the probability of an event, we need to simulate that event multiple times and record how often the desired outcome occurs. The simulation should closely resemble the situation in question.

In this case, we want to find the probability that 3 out of 4 babies born have blue eyes. To simulate this scenario, we could use the following methods:

A. Rolling a 6-sided number cube 3 times: This simulation would not accurately represent the situation because the outcomes of rolling a number cube are not related to babies' eye colors.

B. Spinning a spinner with 3 equal sections 4 times: Similarly, using a spinner with equal sections would not accurately model the probability of babies being born with blue eyes.

C. Flipping a coin 4 times: This simulation doesn't directly represent the situation either. Flipping a coin only has two possible outcomes (heads or tails), while we are interested in the probability of having blue eyes out of four possibilities (blue or not blue).

D. Picking a card from 10 cards 2 times: This simulation also doesn't correspond to the situation at hand. Picking cards from a deck of 10 cards would not accurately reflect the likelihood of babies being born with blue eyes.

Given the options provided, none of the simulations are ideal for finding the probability. To accurately simulate the situation, we would need a method that models the probability of babies being born with blue eyes.
