1) A bag contains 6 yellow counters, 3 green counters and 2 red counters. What is the probability that the first counter taken is red? (someone already helped with this but there’s more) 2) If the first counter chosen is red, what is the probability that the second counter taken out is also red?

3) If the first counter chosen is green and the second counter chosen is yellow, what is the probability that the third counter is yellow?

4) The probability of choosing yellow as the first choice is 6/11 with the given number of counters in the bag. How many counters might you add so that the probability of choosing green is 6/11?

idont know:-):-):-(:-((::)

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
