Question 179819: Please you help me solve these problems.
How do you know, Can you write everything that you solve its?
1.) The table below shows the results of pulling one marble from a bag of marbles, recording its color, and replacing it in the bag.
-------------------------
Marble Color / Times Pulled(#)
--------------------------
Yellow..................>5
--------------------------
Red.......................>17
--------------------------
Green.....................>30
--------------------------
Find the experimental probability of each event.
1.1) Choosing a yellow marble
1.2) NOT choosing a red marble
1.3) Choosing either a red or a green marble
1.4) Which color marble is probably present in greatest number in the bag?
2.) Clarice has 7 new CDs; 3 are classical music and the rest are pop music. If she randomly grabs 3 CDs to listen to in the car on her way to school, what is the probability that she will select only classical music?
3.) Tom has a dollar's worth of dimes and dollar's worth of nickels in his pocket
a. What is the probability he will randomly select a nickel from his pocket?
b. What is the probability he will randomly select a dime from his pocket?
4.)Frank is playing darts. The results of his throws are shown in the table below. Assume that his results continue to follow this trend.
---------------------------
. Color Hit / Number of Throws .
---------------------------
Blue ....................>12
---------------------------
Red........................>5
---------------------------
White.......................>2
---------------------------
Find the experimental probability of each event.
4.1 Frank's next throw will hit white.
4.2 Frank's next throw will hit blue.
4.3 Frank's next throw will hit either red or white.
4.4 Frank's next throw will NOT hit red.
Please answer me as soon as you could, Thank you for your help.

You can put this solution on YOUR website! 1.) The table below shows the results of pulling one marble from a bag of marbles, recording its color, and replacing it in the bag.
-------------------------
Marble Color / Times Pulled(#)
--------------------------
Yellow..................>5
--------------------------
Red.......................>17
--------------------------
Green.....................>30
--------------------------
Find the experimental probability of each event.
1.1) Choosing a yellow marble......5/52
1.2) NOT choosing a red marble.....17/52
1.3) Choosing either a red or a green marble...(17+30)/52 = 47/52
1.4) Which color marble is probably present in greatest number in the bag?..Green
-------------------------------------------------------------------------
2.) Clarice has 7 new CDs; 3 are classical music and the rest are pop music. If she randomly grabs 3 CDs to listen to in the car on her way to school, what is the probability that she will select only classical music?..3C3/7C3 = 1/35
----------------------------
3.) Tom has a dollar's worth of dimes (10) and dollar's worth of nickels (20) in his pocket
a. What is the probability he will randomly select a nickel from his pocket?
Ans: 20/30 = 2/3
--------------------
b. What is the probability he will randomly select a dime from his pocket?
Ans: 10/30 = 1/3
----------------------
4.)Frank is playing darts. The results of his throws are shown in the table below. Assume that his results continue to follow this trend.
---------------------------
. Color Hit / Number of Throws .
---------------------------
Blue ....................>12
---------------------------
Red........................>5
---------------------------
White.......................>2
---------------------------
Find the experimental probability of each event.
4.1 Frank's next throw will hit white...2/19.
4.2 Frank's next throw will hit blue...12/19.
4.3 Frank's next throw will hit either red or white...12/19
4.4 Frank's next throw will NOT hit red...14/19.
