Thare are 2 yellow 3 pink and 5 blue. What is the possibility of drawing two pink marbles of the first one is NOT placed back in to the bag before the second draw

Question

Plz help I need answer as soon as possible

Answer 1

So first, you add up all the marbles. 2+3+5=10. The chance of drawing a pink marble the first time is 3/10 (3 pink marbles, 10 total). To draw a second pink marble, the chance is 2/9 (9 marbles left, only two pink marbles left). Multiply. 2*3/10*9=6/90=1/15.
