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
1/2 Because there is 2 white counter and 1 black and there is a chance you will get white. But a probability getting white is that there is 2 white counters. SM
The probability is zero, because there are no red balls in the bag.
It is (1/2)5 = 1/32
Number of possibilities for one category / Total of all possibilities. For example, if I had a bag of marbles where there are three white marbles and two black marbles. The probability of pulling out a white marble is how many white marbles are in the bag which is: three. But the total of things you can draw out of the bag can either be one of the three white marbles or one of the two black marbles. 3 white marbles+ 2 Black marbles= five marbles. Possibility is 3/5 for drawing a white marble.
35% white,20%blue,15%tan,10% red and green and 5% black and yellow
The probability of drawing a white marble is .46
This is a law of addition probability which states that the probability of A or B equals the probability of A plus the probability of B minus the probability of A and B. Written in mathematical terms, the equation is: P(AorB) = P(A) + P(B) - P(AnB) where P(AnB) = 0 (since you can not pull out a green and black ball at the same time). Let P(A) = Probability of drawing the green ball & let P(B) = Probability of drawing the black ball. Total outcomes is 17. So, P(A) = 4/17 & P(B) = 6/17. Therefore P(green or black) = 4/17 + 6/17 = 10/17.
The odds of drawing a white chip are 18,18181818%. Or 2 chances on 11
It is (4/8)*(6/8) = 3/8
A drawing done in only one color. a black and white drawing is considered monochrome, as the "color" would be black on a white tapestry.
It depends on how many marbles of each colour you have....
Since the box contains 16 marbles, seven of them white, then the probability of drawing one white marble is 7/16. If you replace the marble and draw again, the probability of drawing another white marble is still 7/16. The net probability of drawing two white marbles, while replacing the first, is 49/256.
Black and white black and white black and white and green is a ragga son.
1/2 Because there is 2 white counter and 1 black and there is a chance you will get white. But a probability getting white is that there is 2 white counters. SM

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 probabiltiy it will be black is if the grandparents are white or if the relitives that are 1st might be the soulution
