today i will be doing two blogs because thats how many i need to do to be caught up this week. this first blog is a review on 16 -1 probability. just to review mutually exclusive is P(A or B) = P(A) + P(B). most of your answers will be in fraction form so this is not really difficult. an aexample will be prvoided and show you the steps below.
EX: a card is drawn from a shuffled deck of 52
a) black card
26/52 = 1/2
b) a spade
13/52 = 1/4
c) not a spade
52-13 = 39
39/52 = 3/4
