Since we have been doing probability for the past few weeks so this week I am going to review how to work probability problems. I've already did a blog on probability so this should be really easy to remember. Blogging is so much fun!

Here's a few things that you will want to know about

Robability:

• If two events are mutually exclusive, then they cannot happen at the same
  time.
• P(A or B) = P(A) + P(B) - P(A & B).
• If the events are mutually exclusive, then P(A or B) = P(A) + P(B).

Know that we've reviewed some notes we can work a few examples!

Example 1: A standard deck of cards consists of 52 cards, with 13 cards in each of four suits (clubs, spades, diamonds, and hearts). Clubs and spades are always balck, while diamonds and hearts are always red. The face cards are the jacks, queens, and kings. If the deck is shuffled correctly, what is the probability that the card is:

• A black card = 26/52 = 1/2
• A red club = 0/52 = 0
• A card = 52/52 = 1
• An ace = 4/56 = 1/14

That's about it on probability. Hopefully you remembered everything!

Adiosssss!
