Best ResponseYou've already chosen the best response.0are you using \(\large \cup_{x=1} ^{n} X_i = P(x_1 \cup x_2 \cup x_3\cup x_4 \cup x_5) \)

Best ResponseYou've already chosen the best response.0\[P(X \ge 1)=\frac{1}{32}+\frac{1}{16}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}=\frac{1+2+4+8+16}{32}=\frac{31}{32}\] another method \[P(X=0)=\frac{1}{32}\]\[P(X \ge 1)=1P(X=0)=1\frac{1}{32}=\frac{321}{32}=\frac{31}{32}\]

Best ResponseYou've already chosen the best response.0I've done both with and without compliment, the compliment method is much faster anyway

Best ResponseYou've already chosen the best response.0another equivalent reasoning, can be this: the even space contains 32 possible events, nevertheless only one event, of them, is like this: BBBBB, where B stands for boy, so the total number of favorable events is 31
