Answer 1

Answer:

Hello!!

These marbles are placed in a bag and two of them are random drawn.

2 yellow, 3 pink & 5 blue.

What is the probability of drawing two pink marbles if the first one is NOT placed back into the bag before the second draw?

The probability of drawing two pink marbles if the first one is not placed back into the bag before the second draw is  $\frac{1}{15}$

Step-by-step explanation:

there is a total of 10 marbles, 3 are pink

the probability of selecting pink on first draw is  3/10

after the first draw, there are now 9 marbles total and 2 are pink so the probability of selecting pink is 2/9

multiply: $\frac{3}{10}$ x $\frac{2}{9}$ = $\frac{6}{90}$ = $\frac{1}{15}$ simplified

Hope this helps!!
