On a stretch of highway, the probability of an accident due to human error in any given minute is 10 5, and the probability of an accident due to mechanical breakdown in any given minute is 10 7. Assuming that these two causes are independent:
(a) Find the probability of the occurrence of an accident on this stretch of highway
during any minute.
(b) In this case, can the above answer be approximated by P(accident due to
human error) P(accident due to mechanical failure)? Explain.
(c) If the events in succeeding minutes are mutually independent, what is the
probability that there will be no accident at this location in a year?

step-by-step

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
