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).
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
What is the probability that exactly 3 of the 10 are left handed?
very high, that is only slightly higher than average.
The probability that an individual is left handed is 0.11 In a class of 40 students what is the probability of finding five left handers?
If the probability of a person being left handed is .11, then the probability of a person being right handed is .89 (1.00 - .11). In a class of 40 people, there are 40! (40 factorial) = 40 x 39 x 38 x .... x 3 x 2 x 1 possible Permutations of students. Within this number, there are many that will yield exactly 5 left handed people. 40-P-5 is the number of Permutations of 5 within a class of 40 (sorry, can't use the correct formating here!): = 40! / (40 - 5) ! = 40! / 35! = 40 x 39 x 38 x 37 x 36 Since we don't care about order..... we need to factor out the number of identical permutations. 40-C-5 = 40-P-5 / 5! So.... (40 x 39 x 38 x 37 x 36) / (5 x 4 x 3 x 2 x 1) = 658,008 Now, what is the probability of any one such combination? (.89 to the power 35) x (.11 to the power 5) = 0.000000273 So the probability of exactly 5 left handed people in the class is 658,008 x .000000273 = 17.9408137 %

What percentage of prisoners are left handed?
I see no reason why the percentage should be different than among the population in general - in other words, it doesn't seem reasonable to assume a correlation between being left-handed and being a criminal - or being left-handed and being put into jail.
Is left handed better than right handed?
I think left cause most people are right handed so being left handed is rare so that's good but which ever hand you write with it doesn't matter. But I'm left handed so.
