Four Hundred Accidents That Occurred on a Saturday Night Were $\quad$

question 248

Short Answer

Four hundred accidents that occurred on a Saturday night were analyzed. The number of vehicles involved and whether alcohol played a role in the accident were recorded. The results are shown below: $\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$${\text { Number of Vehicles Involved }}$
$\begin{array}{l|ccc|c}\text { Did Alcohol Play a Role? } & 1 & 2 & 3 \text { or more } & \text { Totals } \\\hline \text { Yes } & 54 & 97 & 19 & 170 \\\text { No } & 27 & 174 & 29 & 230 \\\hline \text { Totals } & 81 & 271 & 48 & 400\end{array}$

Suppose that one of the 400 accidents is chosen at random. What is the probability that the accident involved alcohol or a single car?
A) $\frac { 197 } { 400 }$

B) $\frac { 17 } { 40 }$

C) $\frac { 81 } { 400 }$

D) $\frac { 27 } { 200 }$

• A) \(\frac { 197 } { 400 }\)
• B) \(\frac { 17 } { 40 }\)
• C) \(\frac { 81 } { 400 }\)
• D) \(\frac { 27 } { 200 }\)
