Question 1191632: If you flip a coin 10 times, what is the probability that the first one is heads, the 2nd tails, the 3rd heads, the 4th is tails, and so on (keeps alternating for all 10 coins)?
What I did was do 5/10•5/10•4/10•4/10... and so on until I got to ten coin flips. Doing this gave me a completely different answer from my answer key, please help me fix my mistakes! Thanks!
