Answer 2

✧ Given :

• 5 red and 3 black balls in a bag.

✧ To Find :

• Probability of drawing a black ball ?

✧ Solution :

We have,

➠ Red balls = 5

➠ Black balls = 3

➠ So, Total Balls = 5 + 3 = 8 Balls.

We know that,

${ \pink{ \underline{ \boxed{ \sf{P (E) = \frac{ Number \: of \: favourable \: outcomes}{Total \: Number \: of \: favourable \: outcomes}}}}}}$

• Now, Substitute the values :-

${ \sf{P (black \: ball) = \frac{3}{8}}}$

${ \blue{ \underline{ \boxed{ \sf{ ∴ Probability \: of \: black \: ball \: is=\frac{3}{8}}}}}}$
