1/3 Probability both are red
red picked first:
6/10
red picked second:
5/9 (9 as first red marble not replaced so 5 red marbles remaining and 4 blue marbles still)
6/10 * 5/10 = 1/3
Hope that helps!!
Answer:

Step-by-step explanation:
To find slope using two points you need to find the difference in x and y. You use 
So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x
<span>The ratio of 3 to 4 can be written in all the following ways except 4/3. </span>
if the length is 8ft and the width is (7+x) then the area would be 56+8x, if x is unknown.
I think it’s b but don’t take my word for it
