In a survey conducted among Grade 10 students at Shree Sharada Secondary School regarding the ideal destination for an educational excursion—Pokhara, Lumbini, or Ilam—it was observed that 40 students favored Pokhara, 30 preferred Lumbini, and 45 chose Ilam. Additionally, 15 students considered all three destinations suitable, while 5 students offered no response.
If , , and represent the sets of students who prefer Pokhara, Lumbini, and Ilam respectively, state the cardinality notation for the set of students who found all three locations suitable.
Represent the provided information in a Venn diagram.
Determine the total count of Grade 10 students enrolled at Sharada Secondary School.
Had the 5 students who withheld their opinion chosen Lumbini as a suitable option, what would be the ratio between students who selected only Pokhara and those who selected only Lumbini?
