Diseases I and II are prevalent among people in a certain population. It is assumed that10% of the population will contract disease I sometime during their lifetime, 15% will contract disease IIeventually, and 3% will contract both diseases.(a) Find the probability that a randomly chosen person from this population will contract at least onedisease.(b) Find the conditional probability that a randomly chosen person from this population will contract bothdiseases, given that he or she has contracted at least one disease.

what?

step-by-step explanation:

gdp is the best phrase!

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.

just pick what you think i need more time let me know if this
