Answer: 1/70
Step-by-step explanation:
This is a question that can also be interpreted as what is the probability of having the first number of a phone number to be 8 and the last number of the phone number to also be 8. This answer gives the fraction of the phone numbers that starts with 8 and end with 8.
Since three numbers (0,1,2) cannot start a phone number and we are left to pick from 7 numbers,
then the probability of figure "8" starting phone number = 1/7
Since all 10 numbers can possibly end a phone number,
then the probability of having figure "8" as the last digit of a phone number = 1/10
Hence probability of having "8" as the first and last digit of a phone number = fraction of total telephone numbers that begin with digit 8 and end with digit 8 = 1/7 × 1/10 = 1/70.

Answer:
(a) ED and AC are distinct lines that intersect <u>True</u>
(b) A and C are distinct points that are collinear <u>True</u>
(c) Another name for plane X is plane F
(d) A, B, C, and <u>D</u> are distinct point that are coplanar
Step-by-step explanation:
The conditions that uniquely define a plane includes one or more of the following properties of an Euclidean space of any given dimensions
1) The location of three non-collinear points
2) A given line with a point that is not on the line
3) Two intersecting and distinct lines.
