Answer:
18/25
Step-by-step explanation:
Probability is number of outcomes of interest/total number of outcomes
This said we can first find the number of outcomes of interest.
This means the number of cards that are not red.
12+20=32
There are 32 non red cards.
Next we find the total number of outcomes. This is the total number of cards.
18+12+20=50
So the probability that she does not select a red card is 32/50
We can simpify that by dividing both the numerator and denominator by 2.
18/25
