In a parking lot there are only white cars, green cars and red cars. If one car is selected at random from the lot, the probability that the selected car would be green is 1/6, and the probability that the selected car is red is 1/8 what is the probability that it would be a white car

Hellohaylow. The number 1 represents certainty. A car has been selected, so we're certain that it must be white, green or red. Therefore, the three probabilities must add up to 1. We could pick a symbol, for the unknown probability.
x = probability of selecting a white car
What could we do next?
EDIT: Changed 1/x to x
?
x = probability of selecting a white car
What could we do next?
EDIT: Changed 1/x to x
?
Sincerely I am stuck and clueless here. We have to find x?

Yes, but I wasn't thinking carefully when I'd posted 1/x.
x = the unknown probability
1/6 + 1/8 + x = 1
Let us know, if you'd like more help.
