i think qns is bit confusing they not mentioned clearly how many balls
=>if there are only three balls
there is no probability getting both red
bcoz if one girl picks red then for another girl there is no posibility to pick same color(red)
i,e (1/3)*(0/2)=0

=>if there are at least two red colors
then 1/(4p2)! is the probability
i,e first time they may pick yellow and orange
second time (remaining only 2 red balls)
hence prob=1/2

total probability is 3
probability of choosing red ball is 1/3
two girls oicking so 1/3+1/3
probability of red ball is 2/3
answer is 2/3

if there are only 3 balls i.e. yellow, orange and red.. then the probability of both the girls picking red ball becomes zero.. as the events are not mutually exclusive
