Question

A bag contains 4 red and 6 black balls. A ball is taken out of the bag at random. Find the probability of getting a black ball

Answer 1

black ball = 6
red ball = 4
total balls = 10

now probability for black ball = 6/10
I.e. 3/5 in its simplest form

Answer 2

Answer:

Probability of getting a black ball = 3/5

Explanation:

Number of red balls in the bag = 4

Number of black balls in the bag = 6

Therefore,

Total number of balls in the bag = 4+6 = 10

Number of all possible outcomes= 10 ---(1)

Let E be the event that the ball drawn is black .

Then , the number of outcomes favourable to E = 6 ----(2)

So,

P(E) = (2)/(1)

= 6/10

= 3/5

Therefore,

P(E) = 3/5
