we know that
there are two types of probability
(1) Theoretical probability:
Theoretical probability is used to find the chance of a particular outcome
For example: tossing a coin
rolling a die
(2) Experimental probability:
Experimental probability is calculated using data from experiments
For example: A fair coin is tossed 25 times
a die is rolled 10 times
Here , we are given
a bag contains 9 tiles numbered 1-9
and probability of choosing 4 is p(4)
that is
[tex]p(4)=\frac{1}{9}[/tex]
Since, we are finding a chance to get card number 4 out of 9 cards
so, it is theoretical probability.........Answer
