Question

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.) Toss a coin two times B.) Spin a spinner with 4 equal sections two times C.) Roll a six sided number cube two timesD.) Picks a card from 10 cards two times.

Answer 1

Answer:

B.) Spin a spinner with 4 equal sections two times

Step-by-step explanation:

Given that half of the babies born were blue eyes, then the probability of a baby born with blue eye is 50% = 0.5

The probability that 3 out of 4 babies born had blue eyes will be;

0.5*0.5*0.5*0.5=0.0625

This case is similar to the probability of a Spin, a spinner with 4 equal sections spinned two times;

The probability of the spinner in one spin is 1/4 =0.25

If the process is done twice, the probability is : 0.25*0.25 =0.0625

This case is similar to the scenario in question.
