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.)
looks good
Flavia tossed two six-sided number cubes and added the numbers together. Which outcomes have a probability of 1/12? Select two answers.
A. 3****
B. 4
C. 5
D. 7
E. 10***
E. looks good
10 is two less than the max (12)
3 is one more than the min (2)
the "distribution" is symmetric
The correct answer is A. Toss a coin 5 times and count the number of heads.
To determine the probability of having more girls than boys in a family of 5 children, we can use a simulation to model the problem. In this case, we can simulate the gender of each child using a coin toss. Assigning heads to girls and tails to boys, we can toss the coin 5 times and count the number of heads (girls) we get.
By repeating this simulation many times and keeping track of the number of times we get more girls than boys in a family of 5 children, we can estimate the probability.
Option B involves tossing a 6-sided number cube, which is not directly related to determining the gender of children.
Option C involves generating random numbers and counting the number of prime numbers, which is not relevant to the problem at hand.
Option D involves drawing cards from a standard deck, which also does not directly relate to determining the gender of children.
