3. A box contains 3 red balls and 2 white balls. Two balls are picked randomly from the box without replacement. The random variable X is the number of red balls, and Y is the number of white balls. a. Find the pmfs of X and of Y. b. Show the calculation of the correlation coefficient between X and Y. c. Explain how, without doing any calculation, you could predict the result found in part b.

investment b is an ordinary annuity with $3,909.64 in the account after one year.

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
