According to a study in a certain city, 40% of workers between the ages of 25 to 34 years were paid hourly rates of $10.00 or more in the year 2003. find the probabilities that among 10 randomly selected in this category

40 is the final : )

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
