Probability can be explained through various examples, out of those in this thread I’m picking up one of those i.e.

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.
