It is IMPOSSIBLE that I will pull out a black marble.
It is UNLIKELY that I pull out a blue marble.
It is LIKELY that I pull out a red marble.

It is EQUALLY LIKELY that the spinner will land on red, green, blue, or yellow.
Coin TossIf you toss a coin there are two possible
OUTCOMES, or results.
HEADS or TAILS
As a class, everyone flip the penny one time.
How many possible outcomes are there?
Keep track by making a tally chart.
Results _________ heads _________ tails
Is this game fair or unfair?
Number-Cube ExperimentIf you rolled two 6-sided dice and added the two
tops together to find the sum, how many possible outcomes are there?
Could you roll a one? two? three? four? five?
six? seven? eight? nine? ten? eleven? twelve?
What sum do you think will MOST LIKELY be rolled in five minutes? Why?
With a partner, take turns rolling two dice and recording your results on a bar graph.
Share group results. Is this game fair or unfair?
Spinner Experiment
Experiment One
Make 25 spins.Record results on a tally
chart.Share results.
Experiment Two
Make 25 spins.Record results on a line
plot.Share results.
Calculate the Probability
T E N N E S S E EWhat is the probability of picking and E?
STEP 1: Count how many Es.STEP 2: Count how many letters in all.
I have a 4 out of 9 chance of picking an E.
Write the probability of each color.
RED= ____ out of ____ chance
BLUE=____ out of ____ chance
YELLOW= ______ out of ______ chance
WHITE= _______ out of _______ chance
