Question

the venn diagram below shows the data collected at a sandwich shop for the last six months with respect to the type of bread people ordered (sourdough or wheat) and whether or not they got cheese on their sandwich. use this data to answer the following questions: what is the probability that a randomly selected customer would order sourdough bread? p(sourdough bread) =

Explanation:

Step1: Identify relevant parts of Venn - diagram

The probability of ordering sourdough bread is the sum of the parts of the Venn - diagram that represent sourdough bread.

Step2: Calculate the probability

The parts representing sourdough bread are the 10% (sourdough with non - sourdough's cheese) and 55% (sourdough with cheese), so \(P(\text{sourdough bread})=10\% + 55\%=65\%\)

Answer:

65%
