Answer:

No, the sum of all the probabilities is not equal to 1.

Step-by-step explanation:

Given

$\begin{array}{ccccc}x & {0} & {1} & {2} & {3} & {P(x)} & {0.001} & {0.007} & {0.033} & {0.059} \ \end{array}$

Required

Determine if the given parameter is a probability distribution

For a probability distribution to exist, the following must be true;

$\sum P(x)=1$

So, we have:

$\sum P(x) = 0.001 + 0.007 + 0.033 + 0.059$

$\sum P(x) = 0.1$

<em>Hence, it is not a probability distribution because the sum of all probabilities is not 1</em>
