Question

does \\( \sum p(x)=1 \\) ?
select the correct choice below and, if necessary, fill in the answer box to complete your choice.
a. no, \\( \sum p(x)= \\) (type an integer or a decimal. do not round.)
b. yes, \\( \sum p(x)=1 \\)

Explanation:

Step1: Sum up the probabilities

$$\sum P(x)=0.001 + 0.018+0.125 + 0.282+0.333$$

Step2: Calculate the sum

$$0.001+0.018 = 0.019$$
$$0.019+0.125=0.144$$
$$0.144 + 0.282=0.426$$
$$0.426+0.333 = 0.759$$

Answer:

A. No, $\sum P(x)=0.759$
