Question

What is the probability that a student has a GPA under $2.0$ or has skipped many classes? $\left(a\right)0.080\left(b\right)0.281\left(c\right)0.285\left(d\right)0.365\left(e\right)0.727$

Short answer

The correct answer is$\left(c\right)0.285$

Step-by-step solution

Step 1. Given

The table is:

Step 2. Concept

The probability of an event=$\frac{numberoffavourableoutcomes}{totalnumberofoutcomes}$

Step 3. Calculation

The likelihood that she has a GPA of less than $2.0$or has skipped several classes is calculated as follows:

$$\begin{gathered} P(<2.0orMany)=80+175+25+\frac{5}{1000} \\ =285/1000 \\ =0.285 \end{gathered}$$

As a result, $0.285$ is the required probability.

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