Saxon Course 2: Lesson 14

Lesson 14

• Problems About Parts of a Whole

• Simple Probability

​Parts of a Whole

​attended
the game

• part + part = whole

• Example: One third of the students attended the game. How many students did not attend the game?

• 1/3 + x = 3/3.

• 3/3 - 1/3 = 2/3.

• Two thirds of the students did not attend the game.

​Probability

• Probability is the likelihood that a particular event will occur.

• Probability (event):

​number of favorable outcomes

​total number of possible outcomes

Example: This number cube has 1 through 6 dots on the faces of the cube. If the number cube is rolled once, what is the probability of rolling a 4?

• Since there is one number 4 on the cube out of six numbers, we can say 1/6!

​Daily Challenge #14
This spinner is divided into four equal

sections: (each answer should be a fraction)

a. What is the probability of this spinner

stopping on 3?

b. What is the probability of this spinner

stopping on 5?

c. What is the probability of this spinner stopping on a number less

than 6?
