a bag contains 3 red , 4 black and 2 white balls . what is the probability of drawing a red and a white ball in two successive draws , each ball being put back after it is drawn ?
p = 2 ∗ 39 ∗ 29 = 427 p = 2 ∗ 39 ∗ 29 = 427 we are multiplying by 2 as there are two possible wining scenarios rw and wr . answer : d .
multiply(multiply(divide(3, add(add(3, 4), 2)), divide(2, add(add(3, 4), 2))), const_2)
