choose 1 answer:
(a) 11

Explanation:

Step1: Find number of English teachers with at least 5 years experience

Add number of English teachers with 5 - 10 years and more than 10 years experience. So, \(9 + 2=11\).

Step2: Find total number of English teachers

From the table, total number of English teachers is 15.

Step3: Calculate the fraction

The fraction is \(\frac{\text{Number of English teachers with at least 5 years experience}}{\text{Total number of English teachers}}=\frac{11}{15}\).

Answer:

\(\frac{11}{15}\)
