Question

in a box there are 6 red balls and 4 green balls if two balls are drawn at random what is probability both are same colour

Answer 1

hii mate!!

Total number of balls in a bag is 6+4=10

Two balls are drawn at random, hence total possible ways of drawing two balls at random is 10C2

Probability of an event is =m/n

Where m=number of favourable cases.

n=total number of cases.

Now probability that both of them is red:

(6C2)/(10C2)
