we cannot find the exact quantity as the total vehicles are not given only the white are given
It is (7+4)/(7+5+4+4) = 11/20
i think 6 out of 9 right? then you simplify to equal 1 out of 3.:)
5/6
1/3
11 marbles total and 6 are blue so probability is 6/11
.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.
17 out of 21
3/5 or .6
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.
1/32
45 __ 91
2/13
The probability is 1.
It is (7+4)/(7+5+4+4) = 11/20
1/4
