Suppose that a person invests in 6 stocks, each with a 40% chance of havingno return, a 30% chance of having a positive return, and a 30% chance of havinga negative return. you may assume that the stocks are independent and the probabilities do not change. let(n1; n2; n3)be the number of stocks with noreturns, positive returns and negative returns respectively.

(a) find the probability that 2 stocks have no return, 2 have positive returns, and 2 have negative returns.
(b) find the probability that at least one stock has a positive return.
(c) find the expected values and standard deviations of n 1; n2 n3.
(d) find the pairwise correlations ofn1; n2; n3.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)

but there’s no any figure there!

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
