Find the theoretical probability of picking a vowel in the word "EXPLORE"

• 3/6

• 4/7

• 3/7

• 1/2

how do you find experimental probability

• P(event) = number of favorable outcomes/number of possible out comes

• P(event)= number of times the event occurs/total number of trials

how do you find sample space

• tree tables

• tables

• tree diagrams

• adding

you randomly chose crust and a style of pizza how many possible out comes are there.

• 4

• 1,2,3,4,5,6,7,8

• 12

• 8

How many possible outfits can you make

(use the fundamental counting principle)

• 6x3x8=84

• 7x4x3=84
