another question (sorry about all these just trying to get this done and learn it before tom.)
Jennie calculated the probabilities of various events involving a coin. What is the probability of a coin landing on heads at least twice when the coin is flipped three times
a. 1/8
b. 1/6
c. 1/4
d. 1/2
*i think it is d and if it is i need work for it* *no matter what i need work*

np.
anyways, This is a pretty easy question to answer. The three possible (winning) outcomes are:
1. Heads, Heads, Tails.
2. Heads, Tails, Heads.
3. Tails, Heads, Heads.
If we look at the possible combination of other (losing) outcomes, we can easily determine the probability:
4. Heads, Heads, Heads.
5. Tails, Tails, Heads.
6. Tails, Heads, Tails.
7. Heads, Tails, Tails.
8. Tails, Tails, Tails.
This means that to throw heads twice in 3 flips, we have a 3 in 8 chance. This is because there are 3 winning possibilities out of a total of 8 winning and losing possibilities.
Good luck 
Yes, it is D.

ok but that is not one of the answers and it can't be reduced

k ty i have 4 more *so sorry*
