Probability and Statistics - Week 6: Lesson 2: Probability Real Life Word Problems
Lesson Objective: to continue to build the students knowledge of probability.
To help students understand probability, work on the following problem as a class:
Probability of a deck of cards: http://www.math-aids.com/cgi/pdf_viewer_8.cgi?script_name=probability_cards.pl&prob1=1&language=0&memo=&answer=1&x=77&y=15
Probability of using a spinner: http://www.math-aids.com/cgi/pdf_viewer_8.cgi?script_name=probability_spinner.pl&denom_6=1&denom_8=1&dtype-1=1&dtype-2=1&language=0&memo=&answer=1&x=126&y=28
Begin to give the students problems such as this...
1. I have a bag containing 8 different colored tennis balls. There is 4 orange balls, 2 blue balls, and 2 red balls. For each of the following questions give your answer in words and in numbers found on the probability line.
