Answer:
Probability of sum of pips on two faces is at least 9 =
Step-by-step explanation:
Experiment: Throwing two fair dice.
Total no of Outcome = = 36
Sample space (list of outcome) is attached.
Let E be the event that sum of pips on two faces is at least 9.
Favorable outcome are where sum is 9 , 10 , 11 and 12.
From Sample space, No. of Favorable outcome = 10
∴
Answer:
Options (C), (D) and (E)
Step-by-step explanation:
Slope of the given line =
Any line having same slope will be parallel to the given line otherwise the lines will intersect.
Therefore, we will find the slope of the lines passing through two points given in the options.
Option A
Slope of the line passing through (12, -13) and (15, -12)
m =
=
=
Therefore, both the lines are parallel having no point of intersection.
Option B
Slope =
=
Both the lines are parallel having no point of intersection.
Option C
Slope =
=
Therefore, both the lines will intersect.
Option D
Slope =
=
Both the lines will intersect each other.
Option E
Slope =
=
Both the lines will intersect each other at a point.
Options (C), (D) and (E) are the correct options.
