(+ means or. + when conditions are optional) 0 0 replyShare gauravkc commented Jan 19, 2018 reply Follow flag RR can be actually of 3 types (R1R2 R2R3 R1R3). GG of 6 and BB of 3. 3+6+3 = 12 Total? You have total 10 out of which any 2 are picked. So 10C2 10C2 = 45 12 / 45 = 4 / 15 0 0 replyShare Chandrabhan Vishwa 1 commented Jan 19, 2018 reply Follow flag IF SAME COLOR BALL IS SIMILAR THEN IN THIS CASE? 0 0 replyShare gauravkc commented Jan 19, 2018 reply Follow flag I didn't get what you are asking 0 0 replyShare Chandrabhan Vishwa 1 commented Jan 19, 2018 reply Follow flag SIR IF SAME COLOR BALL IS SIMILAR MEANS MEANS 3 SAME RED BALL ,4 SAME GREEN BALL AND THEN 3 SAME BLUE BALL 0 0 replyShare gauravkc commented Jan 19, 2018 reply Follow flag It's not same. Probability will be affected by the count, right? Say in a box, there are 20 chocolates, 2 lollipops and 3 candies. Probability that you will draw a chocolate will obviously be more. It can't be 1/3. 0 0 replyShare Chandrabhan Vishwa 1 commented Jan 19, 2018 reply Follow flag THANK YOU SIR 0 0 replyShare Please log in or register to add a comment.
