Two boxes each contain two blue blocks, one white block, and one green block. One block is drawn from each box. The probability of drawing a white block from the first box and a blue block from the second box is most nearly: A 0.5 B^A 0.75 C^* 0.125 D 0.0625

Solution

There are two boxes.

Each contains two blue, one white and one green.

Prob of drawing white from first box = no of white blocks/no of blocks = 1/4 =

0.25

Prob of drawing one blue from second box = 2/4 = 0.5

As these two are independent

prob of drawing one from I and one from second = 0.25 x0.5

= 0.125

So option C is right
