Answer: The probability that the student earned an A on the last test is 0.58.
Step-by-step explanation:
Since we have given that
Total number of students = 24
Number of students earned an A =14
Number of students earned a B = 10
So, Probability that the student earned an A on the last test is given by
[tex]\frac{\text{Number of favorable outcome}}{\text{Total number of outcomes}}\\\\=\frac{14}{24}\\\\=0.58[/tex]
Hence, the probability that the student earned an A on the last test is 0.58.
