16-1 probability

today im teaching you how to find the probability of things. these things mostly include a 52 deck of cards or rolling dice. there are other things you can get probability of but these are the main two we will be dealing with. probabilty is from 0-1 meaning 0 will not happen 1 meaning will happen. the fromula for this is             P(event A)= favorable outcomes / total outcomes. this is really easy and has been done before so here is an example below.



EX: find the probability of each picking out of a 52 card deck that is shuffled well.

a) a black card
26 black cards / 52 total cards = 1/2 is the probabilty

b) a spade
13 spades / 52 cards = 1/4 is the probability

c) not a spade
39 not spades / 52 cards = 3/4 is the probability
