these marbles are placed in a bag and two
of them are randomly drawn.

what is the probability of drawing two pink
marbles if the first one is placed back in the
bag before the second draw?
give your answer as a ratio, reduced to
simplest terms,
hint: multiply the probability of the 1st event by the
probability of the 2nd event to get your answer,

b

step-by-step explanation:

b

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
