Can someone help 

 

 

I can't figure out (a) I thought it was 3/62

 

The table shows the socks that are in your sock drawer. You randomly choose one sock, put it on your left foot, then choose another.

 

 

 

(a) Find the probability of the compound event of choosing a black sock and then a green sock. (Enter your probability as a fraction.) 
 =  ________

There are 32 socks total (16 pairs)   8 socks are black

8/32 chance of getting a black sock

   that leaves 31 socks of which 4 are green

4/31 chance of getting a green sock on your second pick

 

8/32 * 4/31 = 32/992 = 1/31
