On Saturday, you can choose to do your Homework or not. You can also choose Coffee, tea or juice for breakfast. How many possible outcomes do you have? And what is the name of the counting method?
6, Counting Theory
Event A is pulling a red 5 standard deck
Event B is tossing a bicentennial quarter
Find P(A n B)
2/52 * 1/2 = 1/52
P(A) = 0.3
P(B) = 0.45
Find the P(AUB) if events A and B are mutually exclusive.

Formally list out the sample space, if you have the following socks in your drawer, and you must pull out two socks in the dark. White, White, Black, Black, Grey, Grey. Hint: use the first letter only for each color.
{ WW, WB, WG, BB, BW, BG, GG, GW, GB }
You must pull two socks from the drawer in the dark. If there are 6 socks in the drawer and only two are blue, what is the probability of pulling two blue socks?

If A and B are independent events, what is P(AnB)?
0.208 (multiply)
P(M) = 0.2
P(MUX) = 0.55
Find P(X) if events M and X are mutually exclusive.

When two events are Mutually Exclusive, what is the P(A n B)?
zero
Find the probability of rolling a 5, and flipping a Heads, then flipping tails.

Events A and B are Independent. If P(A) = 0.31 and P(B) = 0.2, find P(A n B)
0.062
If A and B are mutually exclusive, explain how you know
P(A U B) = 0.45, P(A) = 0.25, P(B) = 0.2
yes, because P(A U B) = P(A) + P(B)
