2 yellow marbles, 7 red marbles, 1 green marble.....total of 10 marbles
probability of first picking a yellow marble : 2/10 reduces to 1/5
replacing the marble
probability of picking another yellow marble : 2/10 reduces to 1/5
probability of both is : 1/5 * 1/5 = 1/25 <==
Well, there's 360 degrees in a full circle.
If the hand moves 1/4 of a complete revolution, divide 360 by 4.

The minute hand moved 90 degrees.
