1. ## probability --just can't figure it out

I haven't done this type of math in over 13 years and need some clarification since Im taking an online statistics course; hard to reach teacher for help!

A) From the information provided, create the sample space of possible outcomes: A coin and a pentagonal die are tossed.

B)Suppose you are playing a game of chance. If you bet $10 on a certain event, you will collect$500 (including your \$10 bet) if you win. Find the odds used for determining the payoff.

Now for part A)---the pentagonal die is supposed to have 5 sides, correct?

And B) I have no idea. lol.

2. PART A)

Sample Space is pretty simple.
Pentagonal die has 5 sides.
Coin has 2 sides.
# of sides = # of possibilities for each item

The sample space is just a box showing the possibilities.

eg. Sample space for 2 coins.

(H, H) (H, T)
(T, H) (T, T)

Notice how each coin has 2 sides, therefore 2 possibilities. So the box is going to be a 2x2 box. With 2x2 = 4 entries.

So, the sample space for your question should have 2 x 5 = 10 entries. Just some busy work.
