- selecting one person among = selecting one from freshmen or selecting one from sophomores or selecring one form juniors or selecting one from seniors .
no. of chances of selecting one from freshmen = 375
no. of chances of selecting one from sophomores = 293
no. of chances of selecting one from juniors = 187
no. of chances of selecting one from seniors = 126
Therefore , total no. of chances of selecting one =375+293+187+126=981
Therefore % of chance of selecting a juni0r = (no. of chances of selecting a junior /no. of chances of selecting anyone)* - 14 years agoHelpfull: Yes(1) No(0)

- probability
= favourable outcomes/total no.of outcomes *100
total number of students=375+293+187+126=981
no.of juniors=187
probability of finding a junior=187/981 *100
=19.02%
approximately 19% - 13 years agoHelpfull: Yes(0) No(0)
- (187/981)*100=19.06%
