hello friend

let blie balls =x
then, total balls =x+6
the probability of red ball =red balls / total balls
the probability of red balls =6/x+6
the probability of blue balls=blue ball/total balls
the probability of blue balls =x/6+x
the probability of drawing blue ball is 3*(6/x+6)
sum of the probability of red ball + blue ball is is equals to 1 hence, add both you got the x's value
i typed soo long if you like it mark as brilliantist
NOW, WE KNOW THAT THE TOTAL PROBABILITY OF OUTCOMES IS(( 1 ))
hence

tusharkapre17:
no I didn't got the value of x
the equations get cancelled
and value became 0
please solve it on paper and send it to me
ok
hello buddy
hello Tushar please post another question because I can't able to rewrite the answer i am following you so please type a question ( FOR ABHIMANYU) and there i add my picture of the question please do it as soon as possible....
or i can tell you the answer here if you understand
let the blue ball equals to x and red balls equals to 6 so total balls is equals to X + 6 now we know that the probability of blue ball is equals to 3 times the probability of red ball x/x+6=3(6/x+6)----------now solve this you got the answer if you still can't get do the same as i described above
answer is 18
