You draw a marble from a bag that has 4 red, 2 blue, and 3 green. What is the probability you will draw a blue marble.

or about 22%

Step-by-step explanation:

There are 9 marbles in total.

There are 2 blue marbles.

There is about a 22% chance that you would pick a blue marble.

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

if i put something wrong your not gonna like it so rather not say nothing.
