chance and pobablities

what is probablity?

probablity means it can happen or not.

there are 3 main things.

• 1.certain things which will happen

• 2. things that can happen but not certain

• 3. impossible

There is a formula for probablity

probablity - favourable outcome

------------------------------

no.of outcome

lets do some question

1.if there are 6 numbers on dice. find the probability of 5?

ANSWER- total number of outcome - 6

favourable outcome-1

probablity- favourable outcome

-------------------------------

no.of outcome

= probablity = 5/6

In container there are 6 yellow balls,3green balls and 8red balls. find the probablity of yellow balls?

Answer- total no.of balls = 8+6+3=17

no.of yellow balls = 6

probablity = 6/17

So like this probablity is done

all the best soon the revision will come
