Suppose we flip four coins simultaneously: a penny, a nickel, a dime, and a quarter. What is the probability that the penny and dime both come up the same?
Thanks in advance!
The nickel an the quarter doesn't affect it. We list out the possibilities.
p:h d:h
p:h d:t
p:t d:h
p:t d:t
2 out of the 4 combinations work, so the probability is 1/2.
Thanks! I tend to get really confused on these types of problems, so your solution helped me!
