In a college algebra class of 35 students, there are 20 women and 15 men. On the first exam, 5 women and 4 men received A’s. A student is chosen at random from the class. What is the probability that the student is a man or received an A on the first test? Express your answer as a decimal rounded to four decimal places.

The probability that a student is selected ta random is a man or received an A in the exam is 0.5714.

Step-by-step explanation:

In a class of 35 students there are 20 women and 15 men.

Compute the probability of selecting a men as follows:

Compute the probability of selecting a women as follows:

It is provided that 5 women and 4 men received A’s in the first exam.

Compute the probability of a a student getting an A and the student being a man as follows:

Compute the probability of a a student getting an A and the student being a woman as follows:

Compute the probability of a student receiving an A as follows:

Compute the probability that a student is selected ta random is a man or received an A in the exam as follows:

Thus, the probability that a student is selected ta random is a man or received an A in the exam is 0.5714.
