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).
What else can I help you with?
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
About 9 percent of the population is hopelessly romantic If two people are randomly selected what is the probability both are hopelessly romantic?
The probability that both will be hopelessly romantic is .0081 .009^2 = .0081
What is the probability of a person going into the NFL?
It is pretty close to 0. It is estimated as the number of people in the NFL divided by the total population of the world!
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 %

400 people found that 66 were left-handed What percent are left-handed?
66 divided by 400 gives you the fraction of people who are left handed. Multiply by 100 to get your answer.
How many people are both handed?
About 10% of the world's population is estimated to be left-handed.
What percent of engineers are left handed?
Approximately 10% of people are left-handed, so it is reasonable to estimate that around 10% of engineers are left-handed as well. However, there is no specific data available for the percentage of left-handed engineers.
