<span>Using place value to exchange equal amounts when renaming a number is called : Regroup
Simple example for a group is when you try to add up :
86 + 25
86 has 8 group of tens and 6 groups of one
25 has 2 groups of tens and 5 groups of one
after adding that up , now the number has 11 group of tens and 1 group of one, the result of that equation would be : 110</span>

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
