Answer:

1/15

Step-by-step explanation:

When the bag is full (of 10 marbles), there are 3 pink marbles. Thus, the probability of drawing a pink marble is 3/10.

We don't replace that pink marble. So now we have 9 marbles instead of 10. We now have 2 pink marbles in the bag. The probability of drawing a pink one now is 2/9.

Thus, the probability of drawing 2 pink marbles in a row is (3/10)(2/9), or

6/90, or 1/15

Answer: 35
Each triangle adds up to 180 degrees by adding the two angles that you already have the value of (37+108) and subtract it from 180 to get the final angle(x) you get 35

Therefore x=35 :)
