(Hint: Describe your simulation and show or explain your work.) (4 points)

Answer 2

the above question


the probability of heads is P(head) = Number of Heads/Number of trials

or how many times was the coin tossed ( number of trials)

how many heads occurred ( number of H's)

For the children

toss 4 coins at once each coin represents a child

Head = boy and Tails = girl

repeat the experiment 50 times

record each trial.... and the count the number of trials with 3 boys and 1 girl in any order.



then P(3boys, 1 girl) = Number of 1 girl/50
