3/20 (option B)
Step-by-step explanation:
Probability that she will randomly select a yellow hair clip, return it to the purse, then select a blue hair clip = probability of picking yellow and probability of picking blue
Total hair clip = 5 + 2 + 3 = 10
Pr(yellow) = number of yellow/total = 5/10
Pr(blue) = number of blue/total = 3/10
Probability that she will randomly select a yellow hair clip, return it to the purse, then select a blue hair clip = 5/10 × 3/10
= 15/100
Probability that she will randomly select a yellow hair clip, return it to the purse, then select a blue hair clip = 3/20 (option B)
