6. Suppose that a law enforcement group studying traffic violations determines that the
accompanying table describes the probability distribution for five randomly selected people,
where x is the number that have received a speeding ticket in the last 2 years.
XP(x)
00.08
10.31
20.25
30.18
40.10
50.08
Which of the following number of selected people having received a ticket would constitute an
unusual event?

1. 22

2. 1

3. 7

4. 18

step-by-step explanation

e2020 got it right

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

1. supplementary angles

2. acd and bcd
