Question

00 students were asked whether they studied French or German. Results: 27 students studied both French and German. (a) What is the probability that a student chosen at random will study only one of the languages? Note: Write the solution as a decimal or percentage

Answer 1

No. of students who studied only 1 language = 39+30 = 69

Total number of students= 100

P(E)= No.of favorable outcomes/ Total number of outcomes

P(Student who studied 1 language) = $\frac{69}{100}$ = 0.69
