Question 393079
P(even or prime)
P(at least 5)
<pre><font face = "batangche" color = "indigo" size = 4><b>

P(any one roll) = {{{1/6}}}, "OR" implies "ADD" (if events can't both happen
at the same time)

----------------------------

P(even or prime) = P(2 or 3 or 4 or 5 or 6) = P(2) + P(3) + P(4) + P(5) + P(6) =

{{{1/6}}} + {{{1/6}}} + {{{1/6}}} + {{{1/6}}} + {{{1/6}}} = {{{5/6}}}

----------------------------

P(at least 5) = P(5 or 6) = P(5) + P(6) = {{{1/6}}} + {{{1/6}}} = {{{2/6}}} = {{{1/3}}}
