Answer:
Probability of function ' x ' is 
Step-by-step explanation:
Store - 1
Total number of car = 15.
The number of
Black car = 7.
Grey car = 6.
White car = 2.
Store -2
The number of car wishes to buy = 3 car.
The number of black car sold = x .
The probability of 'x' = ?.
P ( x ) = P ( first black ) * P ( second black ) * P ( third is black )
P ( x ) =
= 
So the probability of number of car sold is black or P ( x ) = 
Subtracting 3.14r from both sides, we get c-3.14r=x
