One of the 120 people are chosen at random. Work out the probability that this person is a mole who wanted to stand

This question seems to be incomplete, and sadly after an online search i couldn't find the complete question, so i will answer in a general way how to solve this type of problem.

Ok, suppose that we have N elements, and we select one at random, so all of them have the exact same probability of being selected, so if N elements have the same probability of being selected, the probability for each one will be 1/N.

Now suppose that in those N elements, there are K elements with a particular characteristic, such that K < N.

Then if we want to find the probability of getting one of these K elements, the probability will be K times the probability of each single element, that is 1/N, then the probability is:

P = K*(1/N) = K/N.

I know that this may be hard to follow, but let's see a quick example, there are 6 marbles in a bag, and 2 of them are red, which is the probability of picking one red marble at random?

Here we have N = 6, K = 2

Then the probability is:

P = 2/6 = 1/3 = 0.33

Now, in our problem, we have 120 people, and we want to find the probability that the selected person is a mole.

The problem here is that we do not know the number of moles, then assuming that there are K moles, the probability of selecting at random a mole is:

P = K/120.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
