P(red star) = 4/15
P(green star) = 2/14
P(red, green) = (4/15)(2/14) = 8/210=4/105

There are 3 red marbles 7 blue marbles 6 green marbles and 4 black marbles in a bag a marble is randomly selected from the bag the number one fifth represents the probability of selecting what color?
a black one
If a bag contains 4 black 6 green and 2 yellow marbles and one marble is randomly drawn what is the probability that it is not black?
There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.
A bag containing 4 green 6 black 7 white balls a ball is drawn at randomly probability of finding 2 red balls?
The probability is zero, because there are no red balls in the bag.

A jar contains three colored marbles 10 red 15 green and 25 blue If you were to choose without looking what is the probability of selecting a blue marble?
25/50 gives the probability of selecting a blue marble

There are 6 red marbles 8 blue marbles and 11 green marbles in a bag. What is the probability that you will randomly draw either a red or a blue marble?
The probability is 0.56
What is the probability of randomly selecting one orange triangles and then one red triangle if you have 8 green 8 red 7 blue 5 orange 7 yellow 5 purple assume the the first one is replaced?
The probability is orange / total * red / total, which equals one fortieth. 5/40*8/40 = 40/1600 = 1/40

What the probability that Fred will get a black sweet if there 3 yellow sweets 5 green sweets 7 red sweets 4 purple sweets 1 black sweet?
Step 1: Count the total number of sweets in a "bag"There are 3 yellow, 5 green, 7 red, 4 purple and 1 black sweets. Add all these values up to obtain 20 sweets total.Step 2: Determine the probability of the given eventSince we want to determine the probability of selecting a black sweet out of a "bag", we have:1 / 20 = number of black sweets / total number of sweets
A bag contain 4 green 6 black 7 white balls a ball is drawn at random what is the probability that it is a green or a black ball?
This is a law of addition probability which states that the probability of A or B equals the probability of A plus the probability of B minus the probability of A and B. Written in mathematical terms, the equation is: P(AorB) = P(A) + P(B) - P(AnB) where P(AnB) = 0 (since you can not pull out a green and black ball at the same time). Let P(A) = Probability of drawing the green ball & let P(B) = Probability of drawing the black ball. Total outcomes is 17. So, P(A) = 4/17 & P(B) = 6/17. Therefore P(green or black) = 4/17 + 6/17 = 10/17.
