Question

A bag contains 8 black, 6 white and 5 red ball Find the probability of drawing a black or white balls from it.​

Answer 1

Answer:

14/19

Step-by-step explanation:

possible outcomes =14

total outcomes=19

probability of black or white=14/19

Answer 2

Answer:

Let N(s) be the total number of balls

n(s)=19

Let n(a) be an event of drawing a white ball

n(a)=6

Therefore-p(a)=n(a)÷n(s)=6/19

similarly n(b) is 8/19

Therefore the probability of drawing a white or black ball is 8+6/19

14/19
