___________________________

$Total \: number \: of \: cases = 200 \\ \: \: \: \: \: \: \: \: \: Favourable \: cases = 200 - 12 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 188 \\ \\ \: \: \: Required \: probability = \frac{188}{200} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{47}{50}$
