If the values of the joint probability density of Y1 and Y2 are as shown:
0 1 2 total
0 1/12 1/6 1/24 35/120
1 1/4 1/4 1/40 63/120
2 1/8 1/20 ... 21/120
3 1/120 ... ... 1/20
ttl 56/120 56/120 8/120 1
whew ;-)
ok Find
a) P (Y1=0)
b) P(Y2=1 | Y1=1)
c P(Y2=1)
e Check if Y1 and Y2 are independent or dependent
f Evaluate the correlation coefficient r of y1 and y2
Thanks so much
