The total amount of clips in the box, is:


5+3+3+4=15

Since there are 3 blue clips, the probability of picking a blue clip, is:


(3)/(15)=(1)/(5)

Since there are 4 pink clips, the probability of picking a pink clip, is:


(4)/(15)

The probability of both events happening one after another will be the product of the individual probabilities of each event. Then, the probability of picking a blue clip and then picking a pink clip, is:


(1)/(5)*(4)/(15)=(4)/(5*15)=(4)/(75)

Therefore, the answer is:


(4)/(75)
