32 Just add all the numbers up and divide by how many numbers there are (9).
(8, 11) is the correct solution. x = 8, y = 11
Plug it in:
11-8=3
That's correct.
I think the answer is A but I am not sure. I think you would take the opposite of the y axis.
To find the probability of both of these occurring, you will multiply the probability of choosing a blue marble by the probability of choosing a purple marble (with no replacement after the first one).
Probability of choosing a blue marble: 17/120
Probability of choosing a purple marble: 18/119
17/120 x 18/119 = 3/140
You will have a 3/140 chance of both of these occurring.
I used Excel to create the tables and the graphs.
I attached both the tables and the graphs.
You should replace the numbers of the x-axis (in both graphs) by the numbers as a fraction of pi. Those numbers are also included in the table, so you should not have problems with that.
