Answer 1

The probability that a randomly selected defendant either pled guilty or was sent to prison is

= P(pled guilty) + P(was sent to prison) - P(pled guilty and was sent to prison)

$= \frac{387+561}{1022}+\frac{387+55}{1022}-\frac{387}{1022}$

$= \frac{387+561+55}{1022}$

$= \frac{1003}{1022}$

$\approx 0.981$
