If the probability is 0.54 that Stock A will increase in value during the
next month and the probability is 0.68 that Stock B will increase in value
during the next month, what is the greatest possible value for the
probability that neither of these two events will occur?
A 0.22
B.0.32
C.0.37
D.0.46
E.0.63
順帶問一下，題目裡面的「greatest possible value」有人說是最大機率，
但也有人說是最小機率，到底是那個？
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DS:12個醫生分別的專業是M, S, I, R, T,那麼從事I的人有多少？
(1) M，S和R的人一樣
(2) either half of them are major R or T.
謝謝～
