hypergeom. f(1;13,3,1) * f(1;12,5,1)
There are a total of 25 Marbles The chances are 3 out of 25 drawing a Red marble. 3/25 = 12% chance of drawing a red marble
The probability is 0.56
1 in 7
5:16
5/6
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
25
your probability would be 13/13. you would have a 100 percent chance of getting a green marble
The probability of drawing a white marble is .46
There are a total of 25 Marbles The chances are 3 out of 25 drawing a Red marble. 3/25 = 12% chance of drawing a red marble
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.
Probability of drawing a blue marble first is 4 in 8 (or 50%) Probability of drawing a blue marble second is 3 in 7 (or 42.85714%) Probablility of drawing blue then blue is the two above multiplied 0.5 * 0.4285714 Which is 0.212142407 or 21% or One in Five.
5/15 = 1/3 = 33 and 1/3 percent
the probability is you'd get a green marble any other color is impossible. So, the probability is certain
The probability is 0.56
The probability is B*G/(B+G+R)^2where B = number of Blue marbles G = number of Green marbles and R = number of marbles of other colours.
There is a probability of 3 that it will be blue.
