Question

in taking a multiple - choice test, there are four possible answers for each problem, only one of which is correct. assume that someone guesses randomly on all 25 problems.
what is the probability of getting the first problem correct?
a. 20
b. 0.25
c. 0.20
d. 25
please select the best answer from the choices provided

Explanation:

Step1: Calculate the probability formula

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\).

Step2: Determine the values

Here, the number of favorable outcomes (getting the answer correct) is \(1\), and the total number of outcomes (total number of options) is \(4\).

Step3: Substitute into the formula

Substitute into the formula \(P = \frac{1}{4}=0.25\).

Answer:

B. 0.25
