Let a be a non-empty set and let s = p(a) be its power set. let b be a non-empty subset of a. on s, we define a relation r as r={a, a2) esx s]4,nb= a2 n b} show that r is an equivalence relation 2 marks describe the equivalence classes of r when a = z and b = {1,2,3} 2 marks

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
