The spinner is divided into equal parts. use a tree diagram to find the probability that the spinner will land on a vowel both times, if the spinner is spun twice. a. b. c. d.

Answer is

Step-by-step explanation:

Given is a spinner which is divided into equal parts of three.

One part has E, next part has U and third part has N.

Vowels are E, U comprising 2/3 of the area of the circle.

Tree diagram would be

I spin .... prob 2/3 ...landing on vowel .... ii spin ... prob 2/3 ... landing on a vowel

Hence required probability = product of two probabilities

=

answer: do you still need this?

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'.
