Question

Q! and Q2 A fair six-sided dice has five red faces and one grey painted face. The spinner is spun. If the spinner shows an even number, the dice is thrown.
Work out the probability of getting an even number and the colour grey.

0.4

0.215

0.185

0.066


2) .A is (2, 12) and B is (8, 2). What is the midpoint AB?

(3, 5)

(5, 7)

(4, 6)

(6, 10)

Answer 1

We can't answer the first question, because we know nothing about the spinner (looks like some information is missing).

As for the second question, the coordinates of the midpoint are simply the average of the coordinates of the endpoint, so if we let $M$ be the midpoint of $A$ and $B$, we have

$M=\left(\dfrac{A_x+B_x}{2},\dfrac{A_y+B_y}{2}\right)$

Plugging in the numbers, we have

$M=\left(\dfrac{2+8}{2},\dfrac{12+2}{2}\right)=(5, 7)$
