which of the following experiments would best test the statement, "the probability of a coin landing on heads is 1/2."?

a

toss a coin 1,000 times and record the results.

b

toss a coin twice to see if it lands on heads one out of those two times.

c

toss a coin until it lands on heads and record the number of tries it took.

d

toss a coin twice, if it doesn't land on heads exactly once, the theoretical probability is false.

C toss a coin untill lands on heads and then record.

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.
