If the probability of hitting a target when throwing a dart is five out of seven and if six darts are thrown what is the probability of getting exactly four hits?
Compute the probability of any specific sequence of hits and misses, such as HMHHHM, by multiplying the probabilities of each throw: 5/7 for each hit ("H") and 1 - 5/7 = 2/7 for each miss ("M"). Because there are four hits (and therefore two misses), the multiplication includes four factors of 5/7 and two factors of 2/7; briefly, the product equals 5^4 * 2^2 / 7^6. There are 15 distinct sequences of four hits and two misses. Therefore the probability of getting some sequence of exactly four hits equals 15 times this previous value: 15 * 5^4 * 2^2 / 7^6 = 37500 / 117649 = about 31.87%.
How do you evaluate accuracy and precision?
Accuracy is hitting the same, correct point, sort of like hitting the bulls eye of a target. Precision is less stringent, as long as your data points are clustered together (it's also known as the level of uncertainty or variance), it is deemed precise. Scientifically speaking, experiments have to be both accurate and precise.
Is target a Compound word?
Target is not a compound word.
Why would the use of exact statistical analysis reduce creativity?
People often make the error of assuming that analyzing things means removing creativity from the development process. Actually, the use of exact statistical analysis does not reduce creativity. In business, it allows you to better target your audience so that you can tailor your approach to your target demographic.

What is the probability of hitting a target from one gun 910 from another gun is 710 If both gun are fired at the same time the probability of hitting the target?
the question asks probability of at least one gun hitting the target. = 1 - no gun hitting the target = 1 - (1/10) x (3/10) = 97/100 or 97 %
The probability of hitting a target from one un 910fom anothor target is 710 if both guns are fired at the same timethe probability of hitting the target is?
i think since they are mutually exclusive events the probability would by 9/10*7/10 = 63/100
The probability of a novice hitting a target with any shot is 0.3 given that the archer can shoot 6 arrows find the probability that the target is hit at least twice?
P(at least two hits out of 6)=1-P(1 or fewer hits out of 6)=1-binomcdf(6, .3, 1)=1-.420175=0.579825
If a girl plays darts and the probability that she hits the target is 25 percent and if she throws 10 darts what is the probability that she hits the target at least seven times out of ten?
The probability is 0.0035

What is good marksmanship?
hitting the target accurately and consistently.
How do you determine the probability that four marksmen will all hit a target if each marksman usually hits the target 80 percent of the time?
You would multiply the probabilities. The probability the first marksmen hits the target x the probability the second marksmen hits the target x the probability the third marksmen hits the target x the probability the fourth marksmen hits the target. So you take .80 x .80 x .80 x .80 = .4096 or about 41%. So if they all fire at the target with each having an 80% probability of hitting, there will be about a 41% chance they will all hit. If you actually think about this question, though, you would be wise to hesitate about the answer. What causes marksmen to miss? In general it would be many things, often acting in combination: trembling of the hands, distractions, shifts of the wind, variations in the ammunition being fired, and so on. If all four marksmen are shooting simultaneously, or nearly so, then some of these causes will be acting in the same way on all four. These would include the wind and the environmental distractions, for instance. It's therefore conceivable that when one marksman misses, so will all the others, and (usually) when one marksman hits the target, the others will be able to as well. In this situation the probability that four marksmen will all hit the target will be close to 80%, not 41%. The question itself couches some ambiguities. For instance, at a tournament of 100 marksmen, the probability that some four will all hit their target is likely close to 100%. (Problems like this in interpreting the intended meaning of probability questions go all the way back to the very first book on probability by Christian Huygens in 1657. There was argument among very good mathematicians for a long time about the answer to one of his problems because it had three distinct interpretations.)
