According to an online car seller, 22.25% of preowned automobiles sold are black, 19.34% are white, 17.63% are gray, and 14.64% are silver.

If a preowned automobile is selected at random, find the probability that it is either gray or silver.

The probability that a randomly selected preowned automobile is gray or silver is ____ %.

Answer :

To solve this problem, we need to find the probability that a randomly selected preowned automobile is either gray or silver.

The problem gives us the percentage of cars that are gray and silver:

  • Gray: 17.63%
  • Silver: 14.64%

The probability of an event is expressed as a percentage of the total outcomes. Since we are looking for the probability of selecting either a gray or a silver car, we can add the probabilities of these two events because they are mutually exclusive (a car cannot be both gray and silver simultaneously).

  1. Calculate the probability of selecting a gray car:
    [tex]P(\text{Gray}) = 17.63\%[/tex]

  2. Calculate the probability of selecting a silver car:
    [tex]P(\text{Silver}) = 14.64\%[/tex]

  3. Add the two probabilities to find the probability of selecting a car that is either gray or silver:
    [tex]P(\text{Gray or Silver}) = P(\text{Gray}) + P(\text{Silver}) = 17.63\% + 14.64\%[/tex]

  4. Perform the addition:
    [tex]P(\text{Gray or Silver}) = 32.27\%[/tex]

Therefore, the probability that a randomly selected preowned automobile is either gray or silver is [tex]32.27\%[/tex].
