Answer
It was an unusual event.
Work Step by Step
$65$% $=0.65$
$P(made~a~free~throw)=0.65$
Using the Multiplication Rule (see page 282):
$P(made~8~consecutive~free~throws)=P(made~free~throw~1)\times P(made~free~throw~2)\times P(made~free~throw~3)\times P(made~free~throw~4)\times P(made~free~throw~5)\times P(made~free~throw~6)\times P(made~free~throw~7)\times P(made~free~throw~8)=P(make~a~free~throw)^8=0.65^8\approx0.03186$
$P(made~8~consecutive~free~throws)\lt0.05$. It was an unusual event.
