Probability and Chance By: Mrs. Loyacano

It is CERTAIN that I pull out a black marble.

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.

Use CERTAIN, IMPOSSIBLE, LIKELY, or UNLIKELY in a sentence.

It is EQUALLY LIKELY that the spinner will land on red, green, blue, or yellow.

It is LIKELY the spinner will land on yellow.

Which is the spinner MOST LIKELY to land on?

Which color is LEAST LIKELY to be picked?

Is there an advantage on the possible OUTCOME?

Coin Toss If 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 Experiment If 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 E What 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
