Question #a83d6
1 Answer
Explanation:
Without removing any white chips, the probability of picking a black chip is
#P("black chip") = "black chips" / "total chips" = 8/(8+6)=8/14#
When we remove the white chips, only the total number of chips will decrease in number. That is, there will always be
Since we want the probability of picking a black chip to equal
#2/3 = 8/ x#
where
We can now cross-multiply and solve for
#2x = 8 * 3#
#2x = 24#
#x = 12#
Thus, once we have
Since we started with a total of
