Question

There are two bags. First bag contains 6 red balls and second bag contains 8 black balls. A bag is chosen at random and a ball was chosen from the bag what is the probability that the chosen ball is a black in colour

Answer 1

Dear Student,
The probability of choosing a black ball from a bag of black ball = 8/8 = 1
Probability that the ball chosen from a bag is black = probability of choosing the black ball bag $\times$probability of choosing the black ball from it = $\frac{1}{2}\times 1=\frac{{\displaystyle 1}}{{\displaystyle 2}}$
