A family consisting of three persons—A, B, and C—goes to a medical clinic that always has a doctor at each of stations 1, 2, and
Free_Kalibri [48]

Answer:

Step-by-step explanation:

When A, B,C are equally likely to be assigned to any one of the stations 1,2 or 3

we find that each one assigned to one station has probability 1/3

Also each person is independent of the other.

Probability that

a) All three family members are assigned to the same station

= P(ABC) to same station

= P(ABC) to 1+P(ABC) to 2 +P(ABC) to 3

=3*P(A)P(B)P(C) since independent

=3*(\frac{1}{3} )^3\\=\frac{1}{9}

b) This would be equivalent to 1- all 3 to the same station

= 1-\frac{1}{9} \\=\frac{8}{9}

c) Every member to a different station

A has 3 choices while B has remaining 2 and C has 1

Hence prob = \frac{3*2*1}{3*3*3} =\frac{2}{9}
