Scarllet selects a card at random from a deck that contains 18 red 12 yellow and 20 blue cards what is the probablity that she does not select a red card?

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

215.92 dollars is the answer
