This was very helpful thanks

Hello, I am struggling with a concept. If I draw from a bag of marbles MULTIPLE TIMES (let's say 6 draws/trials) and want to determine the probability of drawing 2 red marbles WITHOUT REPLACEMENT, for example. How would i find the probability of obtaining 2 red out of my 6 draws?? What this be P(R and R) or P(at least two red). Also, how would I calculate??

Look up Probability Explained by Organic Chemistry Tutor

[@CyclonicGD]

I’m gonna pass my test cause of this XD

[@evie1919]

so if I did 4 trials but i'm looking to find the probability of getting exactly 2 marbles during those 4 trials, how would I find that?

Liked! thank you

I'm a 21 year old looking to figure out what are my chances of getting a few skins I want out of basically a loot box... I want 12 there are 177 or 168.

Thanks for the easy-to-understand explanation and illustration.

why did u dip ur heart in poo water? :v

[@Tommynnnnn]

probability of pulling a yellow out of bag is 1/10 or 10%, green is 4/10 = 40%

[@lenanabara889]

most unlikely as un as likey advun likely , most likely and certen

[@monicaz4949]

rewatching. best video by far

[@Lifeissimplebro]

thanks dude for the explanation, by the way I am color blind and believe it or nor I cannot distinguish between the red and green marble. I was very confused at first. I suggest you change the color of the marbles so that everyone can understand

[@CyclonicGD]

Life, am I right?

[@markstice2098]

Why do you multiply the probabilities together?

[@MATHguide]

When two independent events occur, the probability that both happen compounds as a product of their individual probabilities.

[@markstice2098]

I’m asking why, genius.

[@MATHguide]

@@markstice2098 because it works.

[@markstice2098]

Hey Mark. Discount what this moron said, it’s a probability of a probability. That’s why you multiply.

[@nezuscolter1407]

It should be 0.4 on p(r)

[@MATHguide]

Why is that?
