If the values of the joint probability density of Y1 and Y2 are as shown:(adsbygoogle = window.adsbygoogle || []).push({});

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
