Question 71364
{{{Probability = (favourable outcomes) / (total outcomes)}}}.
There are 118 possible people that could be chosen. 35 of them you supervise so there are 35 out of the 118 ways in which one of your supervised people could be chosen.
Probability will be {{{35/118}}}.
The probability that someone will be chosen that you do not supervise will be {{{83/118}}} because there are 83 people of the 118 that you do not supervise.
Convert fractions to decimal as necessary.
