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.

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.
