Question

A lot of 25 bulbs contain 5 defective ones. One bulb is drawn at random

from the lot. What is the probability that the bulb is good.​

Answer 1

$\large \bold{ \underline{ \underline{ \: Answer : \: \: \: }}}$

$\to$ The probability that the bulb is good is 4/5

$\large \bold{ \underline{ \underline{ \: Explaination : \: \: \: }}}$

Given ,

Total possible outcomes = 25

Number of favourable outcomes = 25 - 5 i.e 20

$\large \fbox{ \fbox{ \bold{Probability = \frac{No. \: of \: favourable \: outcomes }{Total \: possible \: outcomes } }}}$

$\to$ P(The bulb is good) = 20/25

$\to$ P(The bulb is good) = 4/5
