Take the 2-minute tour ×  This question was from my CAs. Nothing
has been changed.  A local weatherman forecasts that there is a
65% chance of rain on the coming Saturday and a 65% chance of
rain on the Sunday immediately following that Saturday. What can
you conclude from the above weather forecast? Choose one of the
following options.  A. It will certainly rain during the weekend
(that is, it will rain on at least one of the two weekend days).
B. The chance of rain on Saturday and Sunday is 42.25%.  C. The
weather forecast does not sound right, as P(rain on Saturday)+
P(rain on Sunday) > 100%.  D. The chance of rain on Saturday and
Sunday is greater than 50%, but less than 85%.  E. The chance of
rain on Saturday and Sunday is between 30% and 65%.  F. None of
the above.  Chance of raining on Saturday = 0.65 Sunday = 0.65
Therefore, chance of raining on Saturday and Sunday is 0.65*0.65
= 0.4225  Doesn't this means there are two answers, B and E?
Which is more correct?  share|improve this question If B is cor
