Stratified Random Sampling
The odds of two people selecting the same number out of 1000 can be calculated as follows: each person has 1000 options, and for the second person to match the first, there is only 1 favorable outcome (the number chosen by the first person). Therefore, the probability of both selecting the same number is 1 out of 1000, or 0.1%. This means the odds are 1 in 1000.
Let P(A) = 1/10; P(A) = probability of selecting one people on a basketball team P(B) = 1/35; P(B) = probability of selecting one people on a football team P(C) = 1/10 = probability of selecting one people who plays in both teams P(D) = probability of selecting from either team. P(D) = P(A) + P(B) - P(C) P(D) = 1/10 + 1/35 - 1/10 P(D) = 1/35 or 0.0286

P(x=4) ≈ 0.00001847 or about 1 in 54 145The probability of selecting 4 aces while playing poker with six people is:P(x=4) = 5C4 ∙ 4!/[52!/(52-30)!] ∙ (52-4)!/(52-30)!= 5C4 ∙ 4!(52-4)!/52! ≈ 1.846892603... x 10-5 ≈ 0.00001847which is about 1 in 54 145.

Jobs done at the International Space Station include conducting scientific research experiments, maintaining station systems and equipment, conducting spacewalks to repair and upgrade the station, communicating with mission control on Earth, and participating in public outreach activities to educate and inspire people about space exploration.
As of now, there are currently seven people in space. They are aboard the International Space Station conducting scientific research and maintenance tasks.
Yes, the International Space Station (ISS) typically has a crew of astronauts on board conducting scientific research, maintaining the station, and performing other tasks. The crew size varies but usually ranges from 3 to 6 astronauts.
Yes, a space station can carry people. Space stations like the International Space Station (ISS) serve as habitable artificial satellites in space where astronauts live and work for extended periods of time conducting scientific research and experiments.
Speaking to people remotely.
yes you can call people with a telephone!! who knew!!
The telephone was created so people can communicate with other people...
The most important telephone fact is .......that a telephone is used to call people and secondly the telephone saves time by letting people talk with important businesses.
it was important for people to my a telephone because they wouldn't have to ride all the way to the person's house then talk.With the telephone you don't have to do that.
Does* Yes, up to seven at a time. These are usually from multiple countries worldwide (hence the International space station) and the current (2/24/13) crew is from the US, Russia, and Canada.
