20 marbles total, 10 of which are blue
so, odds of drawing blue are 10/20=.5=50%
If the balls are selected at random, then the probability is 12/95.
It is 1/6.
It is 1/7 if a ball is selected at random.

Oh, dude, let me break it down for you. So, the probability of selecting a white ball from that colorful box is simply the number of white balls divided by the total number of balls in the box. In this case, there are 5 white balls out of a total of 5 white + 8 red + 10 yellow balls. So, the probability is 5/23. Easy peasy, lemon squeezy!
If the balls are selected at random, then the probability is 12/95.
The probability that it contains exactly 3 balls is 6/45 = 0.133... recurring.
The probability is (6/14)*(5/13) = 30/182 = 0.1648 approx.
1/4 chance
It is 1/6.
40/50
I am thinking the anser is 5/8... hope it helps
It is 1/7 if a ball is selected at random.
The probability of drawing a green ball from a collection that only contains red and blue balls is 0%. Since there are no green balls present in the selection, it is impossible to draw one, making the probability zero.

(3/7)*(2/7)=(6/49) You have a 6 out of 49 probability.
