Sum of probabilities

Using the Probability Distributions knowledge point
\[
\sum P(x) = 100\%
\]

Set up equation

Using the Probability Distributions and Complementary Probability knowledge points
\[
P(0) + P(1) + P(2) + P(3) = 100\%
\]

Substitute known values

Using the Probability Distributions knowledge point
\[
17\% + 40\% + 29\% + P(3) = 100\%
\]

Solve for P(3)

Using the Probability Distributions knowledge point
\[

$$\begin{aligned} 86\% + P(3) &= 100\%\\ P(3) &= 14\% \end{aligned}$$

\]
