What does the 2 percent tornado probability from the spc typically mean?
A 2 percent tornado probability typically means that isolated and probably weak tornadoes are possible.
What is the percent of electrons that are predicted to be located in the electron cloud?
All of them.
What does the 30 percent tornado probability from the spc typically mean?
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.
Why can't there be probability density equal to 100 percent in an orbital?
The probability density cannot be greater than 100% because nothing exists with a higher probability, except colloquially. We can say that we have a 110% certainty of something but that is only meant to express how certain we are. Because in reality nothing can be more than 100% in terms of probability density.
How many coulomb in one electron?
1 electron charge = 1.602 x 10-19 coulomb. The answer to the question is: about 16 percent of one billionth of one billionth of a coulomb.
What are the Three Approaches to finding a Probability?
1. subjective probability (intelligent guess) 2. relative frequency (in percent) 3. classical probability (in decimal)
Is the location of an electron in an atom best represented by a probability cloud?
Yes, it is true.
What is the significance of drawing the ninety percent contour of orbitals?
The significance of the ninety percent contour is to determine the probability of finding the most electrons within a region.
What is the probability of 33.3 percent?
The probability of 33.3 percent is 0.333.
What is a probability of 75 percent?
probability of 75 percent = 3/4
How do you find the percent of probability?
You multiply the probability by 100.
Probability that you pass English is 50 percent and the probability that you pass history is 40 percent the probability that you pass both is 30 percent What is the probability that you pass English?
Refer back to the first clause. The answer is 50 per cent!
Probability of rain on monday is what is the probability of no rain on Monday?
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%
Can probability be written as percent?
Yes.
What is the probability of an event not occurring if the probability of an event occurring is 20 percent?
80%
What does probability mean in math terms?
you are finding the probable answer in a question EXAMPLE: Michelle has 10 cards. She is giving 2 to Shannon. What would the fraction, the dot (decimal) and the percent be? ANSWER: The fraction is... 2-10 The decimal is... .20 The percent is...20%
The probability for heart disease in a population is 30 percent the probability for the flu in the population is 50 percent the probability of getting both is 10 percent why or why not?
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.
