The probability that an individual is left handed is 0.1 In a class of 30 students what is the probability of finding at least 5 left hander's?
This is a binomial probability distribution. The number of trials, n, equals 30; and the probability of success is p, which is 0.1. In this problem, you want the probability of at least 5, which is the complement of at most 4. We use the complement because we can subtract from 1 that probability and we will have the solution. The related link has the binomial probability distribution table which is cumulative. Per the table, at n=30, p=0.1 and x = 4; the probability is 0.825. Therefore the probability of at least 5 is 1 - 0.825 or 0.175.
What is a space diagram in maths probability?
A space diagram is commonly used in mathematics. It is a table which represents a range of work to mostly do with probability! Hope it helps
The probability of exactly two heads when a fair coin is tossed 6 times is?
This is a binomial distribution; number of trials (n) is 6, probability of success (p) is 1/2 or 0.5. With this information you can go to a Binomial Distribution Table and find the solution. Within the section of values for n=6 and p=.5, read from the section the probability of 2 which is 0.2344 (see related link for table).

How do you calculate chi square p values?
You could calculate it by integrating the chi-square probability distribution function but you are likely to be much better off using a table in a book or on the web.

What is the probability that a kickoff will go between 60 and 75 yards if the average kickoff is 50 yards with a variance of 49?
Change the data to a standard normal distribution and use the table to calculate the probability (areas). * For 75 yd: Z=(75-50)/7 = 3.57; from table area = 0.9998 (use 3.49 value). * For 60yd: Z=(60-50)/7 = 1.43; from table area = 0.9236. Subtract the two areas and you have the probability; 0.9998-0.9236 = .0762 or 7.62%.
Can you see a normal probability table?
Yes, I have it in a book.
An experiment is conducted in which two fair coins are tossed and the number of heads is recorded. The binomial random variable, X, is the number of heads?
thas so true

How do you use a z table?
A z table is used to calculate the probability of choosing something that is normally distributed. In order to use it, first a z score is needed. A z score is the number of standard distributions a value is away from the mean of the data. In order to find the z score, take the value of the datum, subtract the mean, then divide by the standard deviation. The result is a z score. Look up the z score on the table to find the probability of getting anything equal to or lesser than the value you chose.
In probability why would a table be used instead of a tree diagram?
There is no particular reason. There are times when a table is more useful and others where a tree diagram is better. If the probability of an event changes according to the outcome of an earlier event (for example picking cards without replacing) then a table will be close to useless whereas a tree diagram is perfectly suited.
How do you use a function table?
you use it to calculate numbers
Probability of 2 out of 12 trials being positive if the probability of each trial being positive is 5 percent?
This is a binomial probability distribution; n=12, r=2 & P=.05. Read directly from the table probability of 2 is .099 (plugging this data into my calculator gives 0.09879).
If 20 percent of people who enter store buy something and 3 people enter what is the probability of at least one sale?
The probability of at least one event occurring out of several events is equal to one minus the probability of none of the events occurring. This is a binomial probability problem. Go to any binomial probability table with p=0.2, n=3 and the probability of 0 is 0.512. Therefore, 1-0.512 is 0.488 which is the probability of at least 1 sale.
