∙ 15y agoYou 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.)

∙ 15y agoYou can calculate this probability by multiplying the individual probabilities of each marksman hitting the target: 0.8 * 0.8 * 0.8 * 0.8. When you multiple these probabilities, you get 0.4096, or 40.96%. This is the probability that all four marksmen will hit the target.
A 2 percent tornado probability typically means that isolated and probably weak tornadoes are possible.
The probability density in an orbital cannot be equal to 100 percent because an electron exhibits wave-like behavior in quantum mechanics, meaning it does not have a definite position. Instead, the probability density provides the likelihood of finding an electron in a particular region of space within the orbital. Having a probability density of 100 percent would imply that the electron's position is known precisely, which contradicts the principles of quantum mechanics.
This qualifies as a high-risk outlook. A 30 percent tornado probability typically means that the Storm Prediction Center anticipates a major tornado outbreak with the potential for multiple long-track and violent tornadoes.

The first step to determine the formula of a new substance is to determine the elements present in the substance through experimentation or analysis. Once the elements are identified, the next step is to determine the ratio of atoms of each element in the substance to establish the chemical formula.
The probability of 33.3 percent is 0.333.
probability of 75 percent = 3/4
You multiply the probability by 100.
Refer back to the first clause. The answer is 50 per cent!
IF probability of rain is X percent then probability of no rain is 100- X percent. For example if prob of rain is 80% prob of no rain is 20%
80%
Yes.
Drawing the ninety percent contour of orbitals helps visualize the region in space where there is a high probability of finding an electron. The contour represents the volume encompassing 90% of the total electron probability density, giving insights into the shape and size of the orbital. This information is crucial in understanding chemical bonding and reactivity in molecules.
When determining the probability that two events happen at the same time, you convert the percents to decimals and then multiply the percents together. Therefore, 30 percent, or .3, times 50 percent, or .5 .3 x .5 = .15 Converting back into a percentage, the answer is 15% probability that you will get both. 10% is therefore incorrect.
The probability is 10 percent.
Yes decimals are used in probability; also percent and odds.
40 out of 10 is not possible so the probability is 0.
