Approximately 10 percent of people are left-handed If two people are selected at random what is the probability that both are right handed?
The probability is approx 0.81
If 10 percent of the population is left handed what is the probability that 5 people in 20 will be left handed?
We'd like to know the likelihood that any 5 people chosen from 20 will be left-handed if the probability of being left-handed is assumed to be 10%. Well, 5 people can be chosen from 20 in (20 C 5) = 15504 ways. So, we have (15504)*(.1^5)*(.9^15) = 3.19%. This is a Binomial probability problem, where we are interested in 'k' successes (k = 5, success --> people being left-handed) in 'n' trials (n = 20).
A fair dice has 4 faces numbered 1 to 4 What is the probability of rolling a 2 exactly 3 times in 10 rolls of the die?
The probability is 0.2503

If two events are independent the probability that both occur is?
That probability is the product of the probabilities of the two individual events; for example, if event A has a probability of 50% and event B has a probability of 10%, the probability that both events will happen is 50% x 10% = 5%.

How many Nobel prize vinners are left handed?
Around 10% of the general population is left-handed, so it's estimated that approximately 10% of Nobel Prize winners are also left-handed. However, there is no official data specifically tracking left-handedness among Nobel laureates.
What is the ratio of right handed to left handed people in the US?
I'm not 100% sure about this, but I have been doing a report on asymmetries betweent the right and left hands and the differences in these asymmetries between right- and left-handers, and from the information I have come across the 1 to 9 ratio seems to be pretty well accepted. (10% left-handed / 90% right-handed). Please correct me if you have more specific or up to date info. I believe ur right about that and of that 10%, 70% are males and 30% are females which means that 90% of the world is right-handed and 10% is left, 7% of the world is left-handed males and 3% is left-handed females. I believe you may be wrong because if 10% of people are left handed then 90% of people are right handed then how many people are ambidextrious? ^The amount of ambidextrous people is assumed to be negligible in this case.
What are the odds of a left-handed person meeting another left-handed person?
There are plenty of left handed people, so if you are left handed you'll probably meet another left handed person at some point. Approximately 10% of the population of the United States is left-handed. That means that of every encounter between two people, one in ten will include at least on left-handed person. To find out how many will be between two left-handed people, you multiply 10% by 10%, you get 1%, or one in 100, so the odds of a left-handed person meeting another left-handed person are 1 in 100. Your question doesn't specify "meeting for the first time"; encountering someone you already know changes things a little, since left-handedness can run in families. Also, those odds don't include meetings with more than two people, or research into facts such as there being left-handed conventions, or left-handed baseball pitchers tending to know one another. That's probably not a big deal, though, and there may be sports or occupations that favor right-handers, which balance things out.
What is the probability of exactly 7 boys in 10 births when the birth of any child does not affect the probability of the gender of any other children?
This is a Binomial Probability; p=0.5, n=10 & x=7. Since you want the probability of exactly 7, in the related link calculator, after placing in the above values, P(x=7) = 0.1172 or 11.72%.
