You want to determine the probability that in a family of 5 children, there will be more girls than boys. Which describes one trial of a simulation you could use to model this problem?

A.
Toss a coin 5 times and count the number of heads.

B.
Toss a 6-sided number cube 5 times and count the number of times you get a number less than 3.

C.
Generate 5 random numbers between 0 and 100 and count the number of prime numbers.

D.
Draw 5 cards at random from a standard 52-card deck, replacing each card after it is drawn and count the number of hearts. ( There are an equal number of hearts, spades, diamonds, and clubs in a deck.)

1 answer

since prob(heads) = prob(tails) = 1/2
and prob(boy) = prob(girls) = 1/2

what do you think?
