There are 7 red, 9 blue, 2 yellow and 4 green marbles in a bag. You make 2 draws from the bag without returning the first marble selected back to the bag. What is the possibility you select a green then blue marble at random? Question 3 options: 13/22
7/22 * 4/22 = 28/484
4/22 * 9/21 = 36/462
4/22 + 9/22 = 13/22

( NO LINKS OR YOU WILL BE REPORTED )

3rd option is the correct answer 36/462

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: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
