Each of two urns contains green balls and red balls. urn 1 contains 10 green balls and 14 red balls. urn 2 contains 4 green balls and 11 red balls. if a ball is drawn from each urn what is p(red and red)?
BTW- i really don't know what an urn is, i guess a basket or some small bag, but its not important anyway.here are the answer choices:
a.1/9
b.25/39
c.79/60
d.77/180
i think its b. PLz help when you get the chance and thank you for your time. :)
no, the events are independent, so you multiply the probabities of each event
urn1, prob(red) = 14/24
urn2, prob(red) = 11/15
prob(red and red) = (14/25)(11/15) = 77/180
btw, an urn is an ancient clay pot or jug.
e.g. read: Ode on a Grecian Urn by John Keats
77/180. I dub this…correct!
Urns are what people used to put other people's ashes in. (After they burnt the person.):D I play Skyrim. xD
I don't even have that answer choice, is this correct???
Urns are what people use to put other people's ashes in. My Grandpa was a heavy smoker and now is a silver urn to the left of my fireplace (The irony):D I don't play Skyrim. xP
well that escalated quickly

I couldn't find correct answers alltogether, so I searched them one by one. I got a 66%. I go to Connexus Academy and after any assignment they show the correct answer. This what i got above. I think this should be correct for a while before they change the answers again. Btw this is the Probability Unit Test Part 1. Good Luck!!!! :)
