A restaurant offers Chinese, Thai, and Korean food. The following Venn diagram shows the results of a survey finding the types of food the customers like.
a) Use the diagram to determine (( ∩ )\). (2)
b) Use the diagram to determine (( ∩ ) ∪ (\\)).(2)
c) Use the diagram to determine (
′
).

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

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
