<span>(a)
</span>P (all
B+) = (0.12)(0.12)(0.12)=0.001728=0.1728%
<span>(b)
</span>P (no
B+) = (0.88)(0.88)(0.88) = 0.681472=68.15%
<span>(c)
</span>P (not
one B+) + P (no B+) = 1
P (not one B+) = 1 – P (no B+)
<span> = 1 – 0.681472 </span>
P (at least 1 B+) = 0.318528=31.85%
<span>(d)
</span>B. The event in part (a) is unusual because its
probability is less than or equal to 0.05.
