Jessica caught 60 fish tagged them and put them back into the pond after a few days she caught 100 fish from the same lake and observed that 15 of them were tagged the to the nears test whole number what is the best estimate for the fish population in the lake

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
