If 10 cars are parked a row, then what is the probability that there are exactly 5 cars between 2 particular cars
Probability of occurrence of an event -
Let S be the sample space then the probability of occurrence of an event E is denoted by P(E) and it is defined as
- wherein
Where n repeated experiment and E occurs r times.
Since 2 cars are fix so there are eight places. and they can arranged by 8! Now these two cars also changed by eight places [4X2=8] so that chance 8X8!
So required probability
