There are 200 balls there are 100 white balls 55 red balls 45 black balls if a student randomly picks up a ball what's the the probability that he picks up a red ball?
The probability is: 55/200 or 11/40

What is probability that you pick 3 white balls if you have 3 white balls 1 red ball and 2 green balls?
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%.

A bag containing 4 green 6 black 7 white balls a ball is drawn at randomly probability of finding 2 red balls?
The probability is zero, because there are no red balls in the bag.
There are 2 White 4 Black and 6 Yellow balls in an urn if you select 4 balls without replacement what is the probability that you will select at least two balls with the same color?
If you take 4 balls and there are only 3 colors, there is no way you cannot get 2 of the same color. So 100%

What are the three ways that probability can be expressed?
Probability can be expressed as a ratio, a fraction, or a decimal. For example if there are 4 red balls and 4 white balls in a bucket and you pick one without looking the probability (chance) that you will pick a red ball is a half, because half the balls are that colour. You can say that the probability of that happening is 1/2 or 50% or 0.5 The probability is the same for choosing a white ball. * * * * * There is a fourth way, and that is in the form of odds.
What is the probability of drawing a white ball out of a bag with 2 green 3 white and 5 black?
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
