A game at the school carnival involves drawing colored marbles out of a bag for a prize. If you draw a red or blue marble, you w
in. If you draw a green or yellow marble, you lose. After each marble is drawn, it is put back in the bag. You watch several people play with the following results:
G G G B Y G Y G G B G R B Y G R G B Y Y
Based on your observations, what is the probability that you will win?
A
0.20
B
0.30
C
0.45
D
0.70
All up there are 20 marbles and only 6 of those are chances of winning so we make it into a fraction 6/20 then times 20 by five to get to 100 (what ever we do to the bottom we do to the top) times 6 by five giving you a fraction of 30/100 then divide 30 by 100 giving you 0.30 ANSWER EQUALS = 0.30
