from a medical stand point green eyes are very rare in general. green eyes with black hair is very very rare because usually dark hair means dark eyes.
Picking from this set though: I think it is 8+(13-8)+(15-8) / 28
8+5+7. 20/28, = 5/7 or 0.714. Good odds.

What is the difference between black seed and green seed cotton?
Black seed cotton has smoother seeds and green seed cotton has spiky seeds. This makes it harder to clean green seed cotton than it is to clean black seed, because the green seeds will stick to the cotton fibers.
Can a green eyed man and brown eyed woman have a green eyed daughter?
Yes. Blue eyes are a recessive genetic trait, which means that a brown- or green-eyed person can still carry a gene for blue eyes. In this case, the blue-eyed gene is recessive, or subordinate, to the green- or brown-eyed gene. To be blue-eyed, an individual must have a recessive blue-eyed gene from both its mother and father.

Can a white man with green eyes and a dominican with black eyes can have a baby with green eyes?
Whichever gene is more dominant will pass on to the child. EDIT: Whoever posted the above answer is incorrect. SHORT ANSWER: Brown eyes are more likely, but it's still possible. Indepth: Brown eyes will always be the dominant gene over green. Gene dominance doesn't work on a personal level. It just depends which combination of genes the parents pass. This is why you see siblings with different eye colors. The dad could have brown eyes and still be carrying a recessive gene for green eyes. If he passes those genes instead, then green eyes are much more likely. Likewise, the child could end up with brown eyes while carrying the mother's recessive gene for green eyes, and then pass it to their child. ("skipping a generation")
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.
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.

If A jar contains 5 yellow marbles 16 green marbles and 8 black marbles If one marble is selected at random what is the probability that it is not green?
1 in 52
What is the probability of pulling a black ball and then a green ball if there are 3 red balls 3 green balls 3 blue balls and 3 black balls?
3/12*3/11 = 9/132, or 6.818%.
What is the probability of not picking green if there is 10 blue 5 stripped 8 green 1 yellow 1 black?
The answer depends on how many are picked,whether they are returned after picking and whether the picking is done at random. In a single random selection the probability is 17/25.

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.

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
