Chapter 4, Problem 1CQQ

To determine

To find: The possibility of answering the questions correctly.

Answer to Problem 1CQQ

The probability of answering the questions correctly is 0.2.

Explanation of Solution

Given information:

The chance of answering the correct question is 20%.

Formula Used:

The formula to compute the probability of an event A is:

  $P\left(A\right)=\frac{\text{Number of desired outcomes}}{\text{Total number of outcomes}}$

Calculation:

The probability is calculated as:

  $\begin{array}{c}P\left(\text{Answering question correctly}\right)=\text{Chances of answering a question correctly}\\ \text{=20\%}\\ =0.20\end{array}$

Therefore, the probability of answering the questions correctly is 0.2.
