The probability of randomly choosing 1 blue sock is 7/10. The probability of randomly choosing 2 blue socks in a row is 7/10 x 7/10 = 49/100.
I assume you are selecting two socks (one at a time) from the drawer to wear (for example). There are 6 white + 3 black + 3 brown + 8 gray = 20 socks in all So the probability that the first sock chosen to be white is 6/20 since there are 6 socks and 20 socks in total. 6/20 reduces down to 3/10. The probability that the second sock chosen is also white is 5/19 since there are now only 5 white socks left to be chosen and 19 socks in total (since one sock has been taken out). Thus the probability of both socks being white is: probability = 3/10 x 5/19 = 3/38

The probability is 5/36.
The question cannot be answered properly because the children's genders are not independent events. They depend on the parents' ages and their genes. Furthermore, it is often wrongly assumed that the probability of a boy is 50%. That is simply not true: the latest information shows that the probability of a boy is 52%. However, if you choose to ignore reality then the solution, based on the Binomial(9, 1/2) distribution, is that the probability is 0.1641, approximately.
The probability isP(you have the disease)*P(the test shows positive when testing someone with the disease) +P(you don't have the disease)*P(the test shows positive when testing someone without the disease).The second category is particularly important if the disease is rare but the probability of a type II error is large.

The probability, when the 2-dice total is 5, that one of the two dice shows a two is 1/2. The probability that that die is selected is 1/4.The probability, when the 2-dice total is 5, that one of the two dice shows a two is 1/2.

A pedigree chart is used to show your family tree of traits. An example is if a diagram shows your mom who had brown hair and your dad has red hair and then it shows all of the children they had and shows what color hair they had. The probability of most of the kids or all of the kids having brown hair is much higher then them having red hair.

It shows the probability that the results of the study are due to mere chance.
A probability density function.
The probability is 5/36.
It shows us the likelihood of the occurrence of specified events.
it is basically a model that shows the probability that an eletron exists in that position
