Probability is simple. In this case, it's even easier.
Probability is the outcome. It's the outcome over a set amount of data under specifications.
Now, here you're given everything you need. This girl did 50 entries, each one involving three coin tosses. She grouped them per time, and put them in a list.
The specifics you're looking for is how many groups composed of 2 guys and One girl?
Heads=Female
Tails=Male
I'll bold all the one's involving what you're looking for:
Data:
<span>thh tth tth tht thh htt hth hht hth tth tth hht hth tht tht tth tth thh thh htt tht thh tth hht hth thh tht tth hht thh hhh tth tth hth htt tht thh hhh htt thh htt ttt tht ttt thh hht hth htt hht hth</span>
Counting it out, you can see it adds up to 23 total outcomes with 2 boys and 1 girl.
Probability is measured by: Set data/total possible outcomes
So, here that'll be: 23/50
Now it's just simple division. 23/50=.46
Your answer is .46
