5, 3, 5, and 7 make a sum of 20. So 7/20 would be the probability of find a yellow one. Then, subtract 7 from 20 to find the probably of not finding a yellow one, which is 13/20, or 65%

Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!
The probability of pulling a red or yellow marble out of a bag of 3 green 8 red 8 yellow and 3 black marbles is 16 out of 22, or about 0.73.
20% Total marbles = 35 + 85 + 30 = 150 Yellow marbles = 30 Percentage yellow marbles = number_of_yellow / total_number x 100 % = (30 / 150) x 100 % = 1/5 x 100 % = 20%

5/15 = 1/3 = 33 and 1/3 percent
Total number of marbles in the bag = 6 + 19 + 5 + 19 + 17 = 66Number of yellow ones = 19If drawing perfectly randomly, then the probability of pulling a yellow one = 19/66 = 28.8% (rounded)
5 becaese you will get blue
There are 15 blue marbles, 8 yellow marbles and 27 red marbles for a total of 50 marbles. Since there are no green marbles in the lot, It is impossible to pull a green marble from the lot. The is no probability whatsoever! "There just ain't no green ones to pull."
0No blue marbles in the bag.
The probability depends on the availability of marbles of those colours to the person making up the bag.
