Abag contains five blue marbles, five red marbles, five white marbles, and five black marbles. you draw a marble from
the bag, and then draw another marble from the bag.
do you have a greater probability of drawing two blue marbles if you replace the first marble after you draw it or if you
don't replace the marble?
your answer should include both the mathematical proof and a written statement.

when all marbles are in the bag the probability for all the marbles are 25% but if and when a marble is removed the odds drop

Step-by-step explanation:

5 ÷ 20 = 0.25

4 ÷ 20 = 0.2

0.25 > 0.2

e) none of the above because the measure of angle cba is 101°

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
