The total amount of clips in the box, is:
[tex]5+3+3+4=15[/tex]Since there are 3 blue clips, the probability of picking a blue clip, is:
[tex]\frac{3}{15}=\frac{1}{5}[/tex]Since there are 4 pink clips, the probability of picking a pink clip, is:
[tex]\frac{4}{15}[/tex]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:
[tex]\frac{1}{5}\times\frac{4}{15}=\frac{4}{5\times15}=\frac{4}{75}[/tex]Therefore, the answer is:
[tex]\frac{4}{75}[/tex]
