If you pull 35 marbles without replacement, the answer is 1: the event is a certainty.
If you pull only one marble, at random, the probability is 16/50 = 8/25.
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)
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
It depends on how many yellow-green marbles there are, and on how many total marbles there are. There is insufficient information in the question to answer it. Please restate the question, giving this other information.

The probability of selecting a red marble is 3/9
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.
3 in 10
5 becaese you will get blue
There are 11+10+17+15+3=56 marbles in total. Of those marbles, 11 are blue and 17 are red, so there are 11+17=28 blue and red marbles. Therefore the probability of choosing a blue or red marble is 28/56=.5, or 50%.

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.
