3. A bag contains 8red balls and 6 white balls. Two balls
are randomly drawn one after another without replace
mondo. Find the probability, of getting balls of diffecent colors

Work Shown:

We have 8 red and 6 white giving 8+6 = 14 total

The probability of selecting red is 8/14.

After that ball is not replaced, we have 14-1 = 13 balls left. The number of white balls will not go down since only the red ball count goes down.

The probability of selecting white on the second selection is 6/13

So we can say

P(red first, then white) = P(red first)*(white second, given red first)

P(red first, then white) = (8/14)*(6/13)

P(red first, then white) = (8*6)/(14*13)

P(red first, then white) = 48/182

P(red first, then white) = 24/91

Let's label this as A.

A = 24/91

That way we can come back to it later.

Now let's say we pick white first, then red

So we'd have the following.

P(white first, then red) = P(white first)*(red second, given white first)

P(white first, then red) = (6/14)*(8/13)

P(white first, then red) = (6*8)/(14*13)

P(white first, then red) = 48/182

P(white first, then red) = 24/91

Let B = 24/91

Now we add up the values of A and B

A+B = 24/91 + 24/91

A+B = (24+24)/91

A+B = 48/91

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.
