Probability of getting maximum amount = $\frac{5}{20}*\frac{4}{19}*\frac{3}{18}*\frac{2}{17} = \frac{1}{969}$ Odds in favour $= \frac{1}{969-1} = 1:968$ Hence, option (A) ticked. mcjoshi answered Sep 21, 2016 mcjoshi 20 points comment Share See all 0 reply Please log in or register to add a comment.
