Question

In the given figure the lines AB and CD are intersecting at apoint 'O'.angle AOC =50°, Find angle BOD.​

Answer 1

Answer:

Solution :

Let there be x blue balls in the bag.

∴ Total number of balls in the bag = 5 + x

Now,

p_{1}p

1

= Probability of drawning a blue ball = \frac{x}{5 + x}

5+x

x

p_{2}p

2

= Probability of drawing a red ball = \frac{5}{5 + x}

5+x

5

But it is given that P_{1}P

1

= 2p_{2}2p

2

⇒ \frac{x}{5 + x}

5+x

x

= 2 \times \frac{5}{5 + x}2×

5+x

5

⇒ x = 10
