Gordon rolls a fair dice 162 times.
How many times would Gordon expect to roll a four?

27 times

Step-by-step explanation:

A regular dice usually has 6 sides. A fair dice means you have an equally likely chance of landing on any face.

So we would do 162 ÷ 6 to get 27.

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'.
