A drawer is filled with 7 black shirts, 5 white shirts, and 10 gray shirts.
One shirt is chosen at random from the drawer. Find the probability that it is not a gray shirt.
Write your answer as a fraction in simplest form.

5/11

Step-by-step explanation:

7+5+10=22

fraction of grey t-shirts would be 10/22

simplify it and u get 5/11

Actually it's 6/11

Step-by-step explanation:

it would be 10/22 but simplifed it's 6/11

I also did it and got it correct on Aleks so yeah

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
