hi guys i have some homework and im struggling to work out how to do some of these problems:
1) If you flip a coin 3 times. Whats the probability of getting the order: Heads, tails, heads?
how about first writing down the possible outcomes when you flip a coin 3 times?
Hint: when you toss a coin, you have two possible outcomes: H or T. If you toss a coin three times, the tree tosses are independent of each other. So there are 2*2*2=8 outcomes. Write them down
Another way of doing it: The probability of getting Heads on the first flip is 1/2. The probability of getting Tails on the first flip is 1/2. The probability of tails on the third flip is 1/2. The probability of getting those results on exactly that order is (1/2)(1/2)(1/2).
