1. Carey has a bag of marbles. There are 4 red marbles, 5 blue marbles, and 1 green marble. She conducted an experiment in which she pulled out one marble and recorded the color and then returned it to the bag 50 times. Her results are shown in the table.
red - 22
blue - 24
green - 4
a 1/50
b 1/10
c 2/25*
d 1
8. Felix has a bag of 6 yellow marbles and 6 green marbles. He picks a marble and then puts it back 26 times. The results are shown in the table.
Yellow - 15
Green - 11
a 13.3%*
b 15.4%
c 23.1%
d 42.3%
I took the test and these are the answers.
1. 1/50
2. 1/2 and 50%
3. C and E
4. 13/20
5. 12 times
6.
A flipped coin landing on tails
Rolling an odd number on a six sided number cube
7.
Spinning a spinner with sections that are different sizes
Pulling a red marble out if a bag with 6 red marbles, 3 green marbles, and one yellow marble
8. 15.4%
9,10,11,12
Sorry I can not help with these.

experimental prob(green) = 4/50 = 2/25
theoretical probability(green) = 1/10
experimental prob(yellow) = 0 , there are none
theoretical probability(green) = 0
is this a misprint?
Hi I am with Allo I really need the answers because I am really behind now and I need the answers I don't know how to do this test. I only understand 1 and 2. Please I need the answers.
z is correct, thank you
i now think question one is 1/50
Neither problems posed a question .
omg! sorry I forgot to add them!
1. What is the difference between the theoretical probability and the experimental probability of picking a green marble?
8. What is the percent error of pulling a yellow marble in Felixβs experiment?
