11/19 is the probability 11 over 19 if you cant read it
Fractional is 3/6 or 1/2
the same probability as me shaging your ma tonight gigity
0.8.
The probability is zero, because there are no red balls in the bag.
2/7 = 28.57%

The probability of a simple event is the number of ways to succeed over the total possibilities. So, there are three white balls, and ten balls total. So: P(white) = 3/10
If I have 3 red balls 3green balls 2 white balls & 5black all in one sack what is the probability of finding a white ball?
The probability of picking white is equal to the number of white objects divided by the total number of objects (both white and non-white), assuming that all of the objects are identical other than color. In Geometry, the probability of landing on a white space is the area of the white space divided by the total area.
It is 0.2174, approx.
Once you have picked the first ball, you will have five left to pick from, one of which will be the same color as the first pick, and four of colors that you don't want. The probability of picking the second ball of the same color is then 1/5 or 0.20. P.S. It really isn't fair to have someone else do your homework for you.
The probability that you pick 3 white balls is 0.05 or 5%.----------------------------------------------------------------------------------------------------EXPLANATIONThe probability of first drawing a white ball is: P(W1) =3/6.The probability of drawing a white ball given the event that you already draw awhite ball in the first draw and not replacing it back is: P(W2│W1) =2/5.The probability of drawing a white ball on the third draw given the event that awhite ball was drawn in the first and in the second draw is: P(W3│(W1UW2)) =1/4Now, the probability of drawing 3 white balls one by one with out replacement(taking all 3 balls at a time gets the same analysis and result) is:P(W1UW2UW3) =P(W1)∙P(W2│W1)∙P(W3│(W1UW2)) =(3/6)∙(2/5)∙(1/4) =1/20=0.05 =5%.
The probability is: 55/200 or 11/40
