Answer:

2/10 * 2/10 = 1/25

Step-by-step explanation:

Suppose you have 10 marbles in a bag.

5 black , 2 pink and 3 blue

As if two pink marbles are selected then

for one pink marble

probability = event occurred / total outcomes

= 2/10

Similar probability for an other pink marbles

Probability for the drawing two pink marbles is

P = 2/10 * 2/10

= 1/25
