A box contain 5 red , 4 green and 7 white marbles . one marbles is drawn at random from the box . what is the pribabilty that marble is
1. Not white
2. Neither red nor white

No. of red marbles= 5
No. of green marbles = 4
No. of 7 white marbls = 7
Total no. Of marbles = 16

Therefore, P ( getting nor white marbles ) = 9/16

ii.) No. of green marbles = 4
Therefore, P( getting neither red nor white marbles) = 4/16 = 1/4
