## Probability: picking out ball from bag

In one of my post I’ve explained all of the possibilities of outcomes of tossing a coin, or Picking up a card from well shuffled deck of 52 cards.
Now here is the third one picking a ball out from a bag or bucket.
• Let we have a bag in which we are having 3 red ball, 4 green ball and 5 yellow ball.

Let’s check it out different event,

### Probability of ball from bag

in total we are having 12 balls.
if we are to ask find the probability of
1. Green ball
• sol.  favourable outcomes will be = 4, as we’re having 4 green balls.
then Probability will be = 4 / 12 or 1/3
2. red ball
Probability will be =  3/12 or 1/4
3. Yellow ball
Probability will be =  5/ 12
let’s have some more questions
4.  No green ball.
here we have to think twice for favourable outcomes, no green ball means we can have yellow and red as well so outcomes will be
3 + 5 = 8
Probability will be =  8/12 or 2/3.
5. Any ball
this is a sure event every event is our favourable outcome hence Probability will be =  12/12 or 1.
6. No ball
this is impossible event, no ball should picked out means favourable outcomes will be 0,  Probability will be = 0/12 or 0.
Hence I hope you’ve​ got this topic. If you want to add here something then let me know via comment.
