A spinner with 6 equal sections.

A: Predicting the gender of a randomly chosen art teacher if 1 of 3 art teachers is female
B: Predicting the gender of a randomly chosen history teacher if 12 of 15 history teachers are female
C: Predicting the gender of a randomly chosen biology teacher if 8 of 12 biology teachers are female
D: Predicting the gender of a randomly chosen chemistry teacher if 4 of 9 chemistry teachers are female
E: Predicting the gender of a randomly chosen health teacher if 2 of 4 health teachers are female

Answer 1

Answer: A C E

Explanation:

Answer 2

A: Predicting the gender of a randomly chosen art teacher if 1 of 3 art teachers is female.

C: Predicting the gender of a randomly chosen biology teacher if 8 of 12 biology teachers are female.

E: Predicting the gender of a randomly chosen health teacher if 2 of 4 health teachers are female.

Explanation:

Notice that the spinner has 6 equal sections.

So, all situations that can be simulated with such spinner must be multiples, divisors of 6, or a number least than 6, that way, we could use the 6 equal-section spinner.

Option A uses 1 of 3, Option B uses 8 of 12, and Option E uses 2 of 4.

Therefore, the anwers are A, C and E.
