Step-by-step explanation: the probability of success plus probability of failure equals 1. That is, if 'P' and 'Q' represent the probabilities of an event happening (success) or not (failure) respectively. Thus, P+Q=1.
Since P is given as 3/6, we substitute it into the equation P+Q=1. Therefore, Q=1-P; Q=1-3/6; Q=3/6.
You can try with : 30 x 40 x 10. Volume is 12000 and the surface area: 2*30*40 + 2*30*10 + 2*40*10 = 2400 + 600 + 800 = 3800. This is a surface area between 3200 cm² and 4000 cm².
