1.	It is known that in a box of 100 bulbs 7 are defective one bulb is taken out randomly what is the probability that it is a non defective bulb
Answer» <P>GIVEN: It is known that in a BOX of 100 bulbs 7 are defective To find: One bulb is taken out randomly what is the probability that it is a NON defective bulb Solution: From given, we have, It is known that in a box of 100 bulbs 7 are defective P (defective) = 7/100 one bulb is taken out randomly what is the probability that it is a non defective bulb P (defective) + P (non-defective) = 1 P (non-defective) = 1 - P (defective) P (non-defective) = 1 - 7/100 P (non-defective) = 93/100 Therefore, the probability that the bulb taken out randomly is a non defective bulb is 93/100

It is known that in a box of 100 bulbs 7 are defective one bulb is taken out randomly what is the probability that it is a non defective bulb

<P>GIVEN:

It is known that in a BOX of 100 bulbs 7 are defective

To find:

One bulb is taken out randomly what is the probability that it is a NON defective bulb

Solution:

From given, we have,

It is known that in a box of 100 bulbs 7 are defective

P (defective) = 7/100

one bulb is taken out randomly what is the probability that it is a non defective bulb

P (defective) + P (non-defective) = 1

P (non-defective) = 1 - P (defective)

P (non-defective) = 1 - 7/100

P (non-defective) = 93/100

Therefore, the probability that the bulb taken out randomly is a non defective bulb is 93/100
