Question

I don't understand how "Counting Outcomes and Theoretical Probability" works! There's a question that says:

You toss two coins. Find P (one head and one tail).

Please help!

Answer 1

The possible outcomes are:
H H
H T
T H
T T

The first number represents the first coin and the second number represents the second coin

There are two 1 head - 1 tail possibilities out of four possible outomes.

P = 2/4 = 1/2

Answer 2

thank you!
