Answer:
289/290
Step-by-step explanation:
Given that the chance of Donnell being selected is 1/290 
then P( Donnell being selected )= 1/290
Since Donnell and Maria are both member of a population.
 from probability theorem which gives the likely hood of an event to happen which cannot be more than 1, then the probability of Donnell and Maria to be selected is 1
P(Donnell and Maria)= 1
But the chance of Donnell being selected is 1/290 
Then,
1/290 + P(Maria)= 1
P(Maria)= 1-(1/290)
= 289/290
 the chance of Maria being selected is 289/290
