edit:
That makes the assumption that:
-birth isn't induced for various reasons - people tend to try for induced births more on weekends so that it doesn't interfere with the work week
-the ratio of people born on any given day of the week is 1:1:1:1:1:1:1

If the probability of getting identical is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen at random will not be a twin?
1- P(identical) - P(fraternal) =1-0.004-0.023 =0.973 The probability of being a identical or fraternal twin plus the probability of not being a twin has to add to 1. so 1- probability of being twins=probability of not being a twin ;-)
If the probability of getting identical twins is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen will be a twin?
P(twin)=P(identical)+P(fraternal) P(twin)=0.004 +0.023 P(twin)=0.027 [That's 27 out of 1,000 cases, or 54 persons out of 1027.]
A group of 10 people consists of 5 men and 5 women A committee of 4 is chosen from this group What is the probability that one or more of the committee members is a man?
The probability that there are 1,2,3 or 4 men is 1-(the probability that no men are selected). First we select the first person. The probability that this person is a woman is 5/10=1/2. For second person it is 4/9, then 3/8 and finally 2/7. We multiply these together: (1*4*3*2)/(2*9*8*7)=24/1008. This is the probability that every single person in the committee is a woman. One minus that probability is 984/1008=41/42 which is 97.619% Read more >> Options >> http://www.answers.com?initiator=FFANS
What can you do to get the experimental probability to be closer to the theoretical probability?
The experimental probability is figured out when a person goes through the trouble of actually trying it out. Theoretical probability is when a person comes to a conclusion of what is most likely, based off of the experiment results.
1 In a group of 20 adults 4 out of the 7 women and 2 out of the 13 men were glasses What is the probability that a person chosen at random from the group is a women or someone who wears glasses?
In a group of 20 adults, 4 out of 7 women and 2 out of 13 men wear glasses. What is the probability that a person chosen at random from the group is a women or someone who wear glasses.---P(w or g) = P(w) + P(g) - P(w and g)= 7/20 + 6/20 - 4/20= 9/20
What are consecutive days?
Consecutive means one thing following another in a predetermined order. For people working five days a week, Saturday and Sunday are usually their days off. Since Sunday follows Saturday on the calendar, Saturday and Sunday are called consecutive days off. If the following Monday is a holiday, then Saturday, Sunday, and Monday will be consecutive days off. If a person works Monday and Tuesday and has Wednesday off, then works Thursday, Friday, and Saturday and has Sunday off, that person does not have any consecutive days off.
