Kathleen conducted an experiment in which she drew marbles from a bag one at a time and replaced the marble after each draw. The results of her experiment are shown in the table. According to the results from Kathleen's experiment, what is the probability that she would draw a yellow marble and then draw another yellow marble?
Where is the table....?
Red 10 Blue 4 Green 6 Purple 2 Yellow 8
multiple choice a: 4/225 b:28/435 c: 16/225 d: 32/435
Well, first you have to determine the probability of only drawing a yellow marble. To do that, you have to add all the marbles of all the colors together and make a ratio with that as the demoninator and the yellow marbles as the numerator.
1/30 to 8/30?
8/30 is the probability of drawing a yellow marble. Now you have to multiply that number by itself.
Remember to take it to the simplest terms.
