The expression 3c2 represents the number of ways of:
a. choosing 2 items at a time from a set of 3. c. arranging, in order, 2 items from a set of 3.
b. choosing 3 items at a time from a set of 2. d. arranging, in order, 3 items from a set of 2.
c. select the best answer from the choices provided

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

answer: i wpould go with c
