Question 15
You want to apply for a student visa to country “X”. You can do this through any one of the five application centres, “A”, “B”, “C”, “D” or “E”. To determine which application centre to choose, you collect data. Currently, the embassy has decided to receive 15% of the applications from centre A, 10% from centre B, 25% each from centres C, D and E. Historically, 60% of the applications that come from centre A have been granted the visa, and 80% of the applications from centre B have been granted the visa. Centres C, D and E each had a 50-50 chance of granting a visa or not granting a visa respectively. Then answer the given subquestions.
If a total of 500 applications have been granted a visa, then how many would you expect to have come from centres “C”, “D” and “E” (totally from the three centres)? (Note: If your answer is in decimal, enter it rounded to two decimal places. For example, if your answer is “10.256”, enter it as “10.26”)
