Let
b---> the original amount of blue balls in the bag
p---> the original amount of pink balls in the bag
we know that
b=8+p
p=5
so
b=8+5----> b=13
step 1
Find the total of balls originally in the bag
total =13+5-----> 18
step 2
find <span>the probability that a person will pick a blue ball first
</span>Find P(b)
P (b)=13/18
step 3
Find the probability that a person will pick a pink ball second <span>without replacement
the total of balls now is (18-1)-------> 17
P(p)=5/17
step 4
Find </span><span>the probability that a person will pick a blue ball first and then a pink ball without replacement
</span>(13/18)*(5/17)-----> (13*5)/(18*17)------> 65/306-----> 0.21
the answer is
0.21
