Answer

0.986 probability

Work Step by Step

To find this probability you must find the probability of people sentenced to prison $( (392+58)/1028)$= 0.437 and then find the probability of people who entered a guilty plea $ (( 392+564)/1028)$= 0.929 Now add these probabilities 0.437+0.929= 1.367 Now find the probability of both pleading guilty and being sentenced to prison 392/1028= 0.381 Subtract them 1.367-0.381. The result will be 0.986 probability.
