Question

Probability of getting a non-red ball from bag of containing 4 red, 5 blue and 3 black balls is​

Answer 1

Answer:

8non -red ball

Step-by-step explanation:

5blue+3black

=8non-red ball

Answer 2

Answer:

$\frac{2}{3}$

Step-by-step explanation:

Total Number of balls= 4 + 5 + 3 = 12Balls

Number of non -red  balls (Black and Blue) = 5 + 3 = 8BALLS

TO FIND:

Probability of getting a non-red ball

Solution:

Formula For Finding Propability:

Probability = $\frac{Number .of .Possible .outcomes}{Total.Number .of .favourable .outcomes.}$

                   = $\frac{Number .of.non-red.balls}{Total .number.of.Balls}$

                   = $\frac{8}{12}$                On simplifying

                   = $\frac{2}{3}$
