Question

A Bag contains 4 white and 6 black balls, all of the same shape and same size. A ball is drawn
from a bag without looking into the bag. Find the probability that the ball drawn is:

Answer 1

Answer: 0.4 for a white ball and 0.6 for a black ball.

Step-by-step explanation:

Given :-

10 balls in a back, 4 white and 6 black.

Formula :-

Probability = No. of possible outcomes / No. of total outcomes

Probability of getting a white ball = 4 / 10 = 0.4

Probability of getting a black ball = 6 / 10 = 0.6

Hence, the probability for getting a white and a black ball is 0.4 and 0.6 respectively.

Answer 2

Answer:

It is given that

No. of white balls =4

No. of black balls =6

No. of total balls or possible events =6+4=10

P (not a black ball) = No. of white balls / No. of total balls

Substituting the values

=4/10

=2/5
