Question

section 6.1 homework score: 2/21 answered: 2/21 question 5 complete the following probability distribution table: probability distribution table x p(x) -21 0.1 -2 62 0.5 62 0.2

Explanation:

Step1: Recall probability - sum rule

The sum of all probabilities in a probability - distribution table is 1. Let the missing probability be $p$.

Step2: Set up the equation

We have $0.1 + p+0.5 + 0.2=1$.

Step3: Solve for $p$

First, simplify the left - hand side: $0.1+0.5 + 0.2=0.8$. Then, $p = 1-(0.1 + 0.5+0.2)=1 - 0.8 = 0.2$.

Answer:

0.2
