1. find the probability of getting exactly three tails when four are tossed. 2. Find the probability that a family with four children has exactly four girls. Assume that the probability a girl is born is the same as the probability a boy is born.

3. In exercise 6, what is the probability a girl is born is the same as the probability that the has two boys and two girls in order?

4. compare and contrast the tree diagram for exercise 5 and 6.

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.

definitely a. the others have almost all data points on one side of the line.
