thats all of them

Answer 17

Well assuming your posting of the question is correct, none of the choices is correct. I am sure of the answers 7/20 and 8/20 = 2/5.

My result is 7/50 !

Answer 21

( 3/20 * 8/20 ) + ( 1/5 * 8/20 )

Answer 22

Sorry, I took them as separate probabilities which are correct as I gave them. the combined probability is (7/20) * (8/20) = 7/50
