Answer:

PA: 20, 18, 16, 14, 12, 10

PB: 20, 19, 18, 17, 16, 15

(Pair 3)

Step-by-step explanation:

We need to look for a pair with both sides decreasing.

Pair 1 has the exact opposite of what we need happening. It has the sides increasing, so it is out.

Pair 2 has the Pattern A right, but Pattern B is still going up, so it is also out.

Pair 4 has both sides decreasing but the second term on Pattern A is 3 less than the first term when it should be 2. As a result it is also out.

This leaves Pair 3 as our final answer.

Mae has a number cube with 6 sides that are numbered 1 through 6. What is the probability that Mae will roll an odd number?

Stels [109]

Answer:

C) $P(E) = \frac{3}{6}$

The probability that Mae will roll an odd number

$P(E) = \frac{3}{6}$

Step-by-step explanation:

Step(i):-

Given that Mae has a number cube with 6 sides that are numbered 1 through 6.

n(S) = { 1,2,3,4,5,6,} = 6

Let 'E ' be the event of odd numbers

Mae will roll an odd number

n(E) = {1, 3, 5} = 3

Step(ii):-

The probability that Mae will roll an odd number

$P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}$

$P(E) = \frac{3}{6}$
