Calculating Probability With Venn Diagrams
How to draw a venn diagram to calculate probabilities is the third lesson in the probability outcomes and venn diagrams unit of work.
Calculating probability with venn diagrams. It follows calculating probabilities from two way tables and precedes understanding set notation. Calculation of p b probability of b is represented as p b p b is calculated by adding all values of the set b. Applications and methods include two way tables and venn diagrams. Calculate all items of the venn diagram above calculate p a.
P a only items in the a circle no sharing 0 4 0 2 0 1 0 05 0 75 calculate p b. Read data in a venn diagram example 1. They are asked if they usually buy toasted sandwiches t salads s or burgers b.

Using a 3 circle venn diagram to calculate probability. How to calculate the probability using a venn diagram with a couple of examples. Learn how to calculate and apply probability to solve problems in a variety of contexts.
In each venn diagram a set is represented by a closed curve. Venn diagrams are helpful for thinking about probability since we deal with different sets. Consider two events a and. The probability that a student works part time is p pt 0 5.
