A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bag. What is the probability that the ball drawn is 1)red? 2)not red?​

Answer 1

Answer:

Probability Of Balls Drawn :-

$\frac{number \: of \: certain \: colour \: of \: ball}{total \: number \: of \: ball}$

The Probability Of Ball Drawn Is :-

a)Red

$\frac{number \: of \: red \: balls}{total \: number \: of \: balls } \\ = ) \frac{3}{8} \:$

b)Not being red:-

$\frac{number \: of \: non \: red \: balls}{total \: number \: of \: balls } \\ = ) \frac{5}{8}$
