1 Answer
Explanation:
You can only get 3 distinct combinations using 3 coins. Either 1 head and two tails, 2 heads and 1 tail or 3 heads. Below are the possible configurations
The total amount of combinations between the 2 coins is
Thus
This simulation confirms the results using R
n<-0;
t<-100000;
for(i in 1:t)
{
boy1<-round(runif(3,0,1));
boy2<-round(runif(3,0,1));
if(sum(boy1)==sum(boy2) && sum(boy1)>0){n=n+1;}
}
n/t
this resulted in 0.29444
