Answer from: HannaTheGurls

P=0.3698 or 36.98%

Step-by-step explanation:

Complete the table by adding the totals to each column and row.

Pedestrian Pedestrian

Intoxicated Not intoxicated Totals

Driver Intoxicated 56 71 127

Driver Not intoxicated 292 522 814

Totals 348 593 941

The probability that the pedestrian was intoxicated or the driver was intoxicated is the opposite event of neither of them was intoxicated. The total of cases when neither of them was intoxicated is 593. So the probability is:

P1=593/941=0.6302

The probability of the opposite event is one minus the probability calculated:

P=1-0.6302=0.3698

And this is the probability that the pedestrian was intoxicated or the driver was intoxicated.

step-by-step explanation:

659

Answer from: Quest

answer: the proof is mentioned below.

step-by-step explanation:

since, given: lines bc = ef

prove: lines ac > ef

statements reason

1. bc=ef 1. given

2. ac= ab+bc 2. because b is the point between the

line segment ac

3. ac > bc 3. because if a line segment is equal to

the sum of two line segments then it is

always greater then each of these

individual line segments

4. ac > ef 4. by equality property.
