May be a very basic Q? But haunting me. Its there in Probability paper But still have queires. simplified it.|
There are two bags one bag 2W 3 R and second bag 4W 5R.What is the prob to draw a red ball?
Ans: is sum of (prob of drawing bag) x (prob of drawing redball)
= (1/2 * 3/5) + (1/2 * 5/9) = 27/52
Real question if i take all the events.
bag1 = A bag2 = B
then events will be
so total prob of drawing red are (3+5)/14= 8/14.
If the approach is wrong where are the rest of the events. Kindly help?
