Two six-sided dice are rolled (one red and one green). some possibilities are (red=1,green=5) or (red=2,green=2) etc.
(a) how many total possibilities are there?
for the rest of the questions, we will assume that the dice are fair and that all of the possibilities in (a) are equally likely.
(b) what is the probability that the sum on the two dice comes out to be 9?
(c) what is the probability that the sum on the two dice comes out to be 12?
(d) what is the probability that the numbers on the two dice are equal?

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
