Answer
a) $\frac{1}{5527200}$
b) $\frac{1}{6250000}$
Work Step by Step
a) If Bo, Colleen, Jeff, and Rohini win the first, second, third, and fourth prizes, respectively out of 50. Then P= $1/50 \times 1/49 \times 1/48 \times 1/47$ =
$\frac{1}{5527200}$
b) If the Same condition holds, but this time one person can win more than one prize. Then P= $\frac{1}{50^{4}}$ =$\frac{1}{6250000}$
