1. To find the number of students who passed in French, we need to add the number of students who passed French only to the number of students who passed both French and mathematics:
Number of students who passed in French = 14 + 23 = 37
Therefore, 37 students passed in French.
2. To find the probability of selecting a student who passed in mathematics, we need to divide the number of students who passed in mathematics (including those who passed both French and mathematics) by the total number of students in the class:
Number of students who passed in mathematics = 23 + 5 = 28
Total number of students in the class = 50
Probability of selecting a student who passed in mathematics = 28/50 = 0.56 or 56%
Therefore, the probability of selecting a student who passed in mathematics is 0.56 or 56%.
Fifty students in a class took an examination in French and mathematics,if14 of them passed French only, 23 passed in both French and mathematics and 5 of failed in both subjects,fine
1.the number of students who passed in French
2.the probability of selecting a student who passed in mathematics
