The hat has no support, so the weight of the ball usually folds the hat downwards
.4
Probability of not blue is the probability of white. The probability of white is 11/(11+21) or 11/32.
There is a probability of 3 that it will be blue.
we cannot find the exact quantity as the total vehicles are not given only the white are given

17 out of 21
That would be based upon the remainder of the probability it could be anything else, depending upon all of the other choices (red, white, yellow, Caucasian...). For example, if there is a 99 percent chance it's white, and the only two choices are white or black, and there are no external constraints that prevent it from being less than random, there would be a 1 percent probability it would be black.

The probability is 1.
It is (7+4)/(7+5+4+4) = 11/20
