Probability that a stone is cracked = 15/600; denote this event by .
Probability that a stone is discolored = 27/600; denote this event by .
Probability that a stone is neither cracked nor discolored = 562/600; in terms of and , this event is captured by .
a. We want to find . Use the known probability of its complement:
b. We want to find . By the inclusion-exclusion principle,
c. By the law of total probability,
Answer:
1/6
Step-by-step explanation: Im going to guess the dice has 6 sides, rolling any number on that 1 dice would be a 1/6 chance. I hope this helps!
Answer:
The value of the length of AC is 14
Step-by-step explanation:
When points are collinear, it simply means that the points lie on the same straight line.
In this question , we have three points which lie on same straight line.
These are points A, B and C with B between A and C.
Thus the length AC can be obtained by adding the length of AB to the length of BC
Mathematically, the value of the length of AC will be 8 + 6 = 14
