so its a repartition of employes based on their professional category and their stress level. C = management, B = Personnel, O = worker E = high stress M = medium and F = low

a) is asking whats the probability that a chosen employee is on management with a low stress level

#

im kinda stuck cuz idk what to choose, i initially did P(A) = 50/20 but that has to b incorrect

#

maybe i have to do 1000/50?
