Question

of 100 students, 23 are taking calculus, 29 are taking French, and 12 are taking both calculus in French. if a student is picked at random what is the probability that the student is taking calculus or French?

Answer 1

Answer:

64 percent

Step-by-step explanation:

the question asks whats the percentage some student would take of any of the two classes. 23 take calculus, 29 take french, and 12 take both. since there are 100 students, 64 take either or both, therefore, theres a 64 percent chance of a student taking either classes.

Answer 2

Answer:

28%

Step-by-step explanation:

Total number of students = 100

Students taking both Calculus and French = 12

Since the question did not say Calculus only and French only, 12 students taking both could be included inside students taking Calculus and French of 23 and 29 students respectively

Students taking Calculus Only = 23 - 12 = 11

Students taking French Only = 29 - 12 = 17

P (Calculus or French) = 11/100 + 17/100 = 28/100 = 7/25
