A class consists of 39 woman and 42 men. If a student is randomly selected, what is the probability that the student will be male?
It would be 3 out of 81.
To find the probability that a student will be male, we need to divide the number of men by the total number of students in the class.
In this case, the class consists of 39 women and 42 men, so the total number of students is 39 + 42 = 81.
Now, to calculate the probability of selecting a male student, we divide the number of men (42) by the total number of students (81):
Probability = Number of desired outcomes / Total number of possible outcomes
= Number of men / Total number of students
= 42 / 81
Therefore, the probability that the student selected will be male is 42/81, which can be simplified to approximately 0.519 or 51.9%.
