Answer: 3
Step-by-step explanation:
Move the decimal back to its point of origin
We are given points

and

.
We first find the midpoint M, of AB, which divides the segment AB into 2 equal parts,
then we find the midpoint N of AM, and midpoint K of MB.
Thus each of the half parts is divided into 2 equal parts. The whole segment is divided into 4 equal parts.
The coordinates of M, N and K are found as follows:
the coordinates of M are:

the coordinates of N are:


similarly, the coordinates of k are:
Answer:
2/3
Step-by-step explanation:
So we have 10%+5%=15% of clients under the condition "permanent", and we can find the probability that a client in that group requested a haircut:
P(haircut | permanent)=10%/15%=2/3
