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%
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.
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.
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.
Subjective based on information given
Assuming the returns are nomally distributed, the probability is 0.1575.
It is 67%.

Probability
P(R) = 0.7The correct choice of answer is B. 71%.
probability
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
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.
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.

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%
