Question

a deli owner made a probability distribution chart for the meat choices of their customers sandwiches when the sandwiches contain only one meat. what is the missing probability in the table? 0 0.09 0.20 0.50

Explanation:

Step1: Sum of probabilities in a distribution

The sum of all probabilities in a probability distribution is \(1\). Let the probability of Tuna be \(x\). Then \(0.28 + 0.31+0.19 + x+0.13=1\).

Step2: Simplify the left - hand side

First, add the known probabilities: \(0.28+0.31 = 0.59\), \(0.59+0.19=0.78\), \(0.78 + 0.13=0.91\). So the equation becomes \(0.91+x = 1\).

Step3: Solve for \(x\)

Subtract \(0.91\) from both sides of the equation: \(x=1 - 0.91\).

Answer:

\(0.09\)
