a bag holds 3 red marbles and 3 green marbles . if you removed two randomly selected marbles from the bag , without replacement , what is the probability that both would be red ?
"given : 3 r and 3 g marbles required : probability that 2 marbles removed without replacement are both red initially we have to pick one red from a total of 3 red and 3 green marbles after one red has been picked , we need to pick 1 red from a total of 2 red and 3 green marbles . p ( both red ) = ( 3 / 6 ) * ( 2 / 5 ) = 1 / 5 option b"
divide(choose(3, 3), choose(add(const_2.0, 3), const_2))
