Question 328012
I assume you mean {{{8 }}}reds?
{{{8}}} Red
{{{5}}} Blue
{{{3}}} Yellow
{{{16}}} total
I assume you mean two are chosen without replacement.
P(1B or 1Y) means P(not both reds)
Find P(not both reds)
P(both reds)+P(not both reds)={{{1}}}
P(not both reds)={{{1}}}-P(both reds)
.
.
.
P(R,R)={{{(8/16)(7/15)=(1/2)(7/15)=7/30}}}
P(not both reds)={{{1-7/30}}}
P(1B or 1Y)={{{23/30}}}
