a box contain 5 red marbles, 8white marbles and 4 green marbles.one marbles is taken out of the box at random what is the probability that the marble taken out will be
red?
white?
not green?
n(s)=5+8+4=17
Let A be the event of taking a red marble
P(A)=5/17
Let b be the event of taking a white marble
P(B)=8/17
Let c be the event of taking not a green ball,
P(C)=1-4/17=13/17
