Step 2. Concept

The probability of an event=numberoffavourableoutcomestotalnumberofoutcomes

03

Step 3. Calculation

The likelihood that she has a GPA below 2.0is calculated as follows:

P(<2.0)=80+1751000=2551000=0.255

As a result, 0.255 is the required probability.

As a result, the best solution is (b).
