Answer:
The answer is B
Step-by-step explanation:
In the decimal (base ten) system, the value of the digits is based on the number ten. Each position in a decimal number has a value that is a power of 10.
Let the total number of cars = 100
Total of sedan, van and sports cars = 39+33+7 = 79
Number of other cars = 100 - 79 = 21.
Let A be the event of owning a sedan,
B be the event of owning a van and
C be the event of owning a sports car.
D be the event of owning other cars.
Then, 
and


Now,
p(non selection of van) = p(A ∪ C ∪ D)
= p(A) + p(C) + p(D)


= 0.67
The probability of none of the three selections would be a van is:
0.67 × 0.67 × 0.67
= 0.300763
=0.301
Hence, the correct option is (D).
