To work this out, you first need to calculate the probability of the first 8 passing, and the final 2 failing. That is 97%8x3%2 which equals 0.070536902349392649%
The next step is to find out how many different ways the people can be ordered. We have 10 in total and want to order 8, so the number is 10C8, which is 45. Multiply this by the above probability and you get 3.174160605722669205%
Thus the probability that 8 of the next 10 will pass is 3.17%

When rolling a die what is the chance of getting a three?
A die can come up showing numbers 1 2 3 4 5 6 and the probability of any number coming up is the same - one out of six. The chance of throwing a three is one out of six. In maths, this is called the probability of throwing a three, and given as a fraction of one, in this case one sixth 1/6. Chance and Probability mean the same thing, but chance is usually given as one out of six or two out of three or fifty/fifty for example. Probability is a mathematical thing and given as a fraction.A probability of 0 means no chance at all and a certainty has a probability value of 1. A mathematical probability of 0.99 means there is a 99% chance of success, or 99 out of a hundred.
The probability of rain on any given day is 40 percent Shirley says that means there is a 60 percent chance it will not rain the whole week she is there. Do you agree?
No. There is a 60% chance that on a given day there will be no rain at a given location in the forecast area. But for two days that reduces to 36% ( .6x.6), and to 21% (.6x.6 x.6 ) for three days, etc., based on probability.
Why can't probability be greater than one or less than zero?
Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen). You cannot have a negative percent for something that will not happen or a percent greater than 100 for something that will happen.
Is the probability that it will rain tomorrow is 28 percent an example of classical probabilityor empirical probability or subjective probability?
Subjective based on information given
When an average rate of return of 16.7 percent and a standard deviation of 43.1 percent What is the approximate probability that this stock will yield more than 60 percent in any given year?
Assuming the returns are nomally distributed, the probability is 0.1575.
If there is a 60 chance of rain tomorrow and a 40 chance of wind and rain what is the probability that it is windy given that it is rainy Round your answer to the nearest percent.?
It is 67%.

What is the word given to the chance of something will or will not happen?
Probability
If there is a 70 chance of rain tomorrow and a 50 chance of wind and rain what is the probability that it is windy given that it is rainy Round your answer to be the nearest percent?
P(R) = 0.7The correct choice of answer is B. 71%.
Which term is defined as the chance that a given event will occur?
probability
What is the probability of rain 5 percent?
It means there is a 5% chance of rain for the given day. If you were presented with 100 days of equivalent conditions, you would expect it to rain for 5 of them
How you can find the brobability as a fraction?
I assume the probability is given a percent, or as odds, i.e. there's a 20% chance or 1 in 5 chance. You convert a percent by dividing by 100, 20% = 0.20, you convert odds by dividing the first number by the second, ie: 1/5 = 0.20.

If there is an 80 percent chance of rain and a 30 percent chance of wind and rain what is the probability that it is windy given that it is rainy Round your answer to the nearest percent.?
To get the answer to this question you need to work out what 30% of 80% is. To do this you need to divide 30, by 80, then multiply your answer by 100. 30/80=0.375, 0.375*100=37.5, 37.5 to the nearest percent is 38%
