It is out right now, just look it up!
3 out of 13 or 3/13
The expected number is 12/7 = 1.29 approx.
3/12*3/11 = 9/132, or 6.818%.
The probability is 3/7 * 2/6 * 1/5 = 1/35.
9 because tom is a guy and he has 3 red balls 4 blu,e balls and 2 balls in a sack
Assuming that you're only drawing two balls out of the bag, your chance of getting two reds would be 3/5 * 2/4 = 3/10, or 30%
20/36
croquet
red and yellow
Please seperate the red balls from the blue balls.
If the balls are selected at random, then the probability is 12/95.
3c2+2c2+3c1 2c1 --------------- 7c2. I have done it this way. 3C2 means that the both balls would be green 2C2 both would be red and 3C1 and 2C1 because both the balls can be red and green.
