The total number of cars in a parking lot is 1342 Out of all

The total number of cars in a parking lot is 1342. Out of all those cars, 417 are white or silver. What is the probability of selecting a car that is neither white nor silver, if picked randomly out of the lot? (Points : 4) 0.389 and 38.9%. 0.589 and 58.9%. 0.689 and 68.9%. 0.489 and 48.9%.

Solution

we use the frequency probability

probability of white or sivelr will be = 417 / 1342 = 0.3107 = 31.07%

so the probability of neither white nor silver is 1 - 0.3107 = 0.689 = 68.9%
