A bag contains blue and pink balls. There are 8 more blue balls than pink balls. Identify the expression that represents the pro
8_murik_8 [283]
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
