Answer:
0
Step-by-step explanation:
From the given information;
Let x be the number of trails on which the defective occurs.
Let the probability that an occurrence of a defective be p = 0.10
Suppose x is a random variable that follows a negative binomial distribution with parameters r and p.
Then the probability mass function of X can be expressed as:
We are to find the probability of the fourth defective engine will be found on the second trial.
i.e. r = 4 and x = 2
Answer: it’s C
Step-by-step explanation:
"Understand the problem" might rightly consist of
• Perform this step first
• Identify what you are being asked to solve or find.
• Identify the important words or numbers in the problem
• Identify any instructions that you are supposed to follow
_____
One of my professors always insisted we start the solution of any problem by writing down what was Given, and what we had to Find, using those headers for the sections of the paper we turned in. Only after those were listed were we allowed to write the Solution. Solution papers that didn't have that format were tossed in the trash, and no credit was given. Harsh, but effective.
Answer:
The correct answer is b) 20.78
Step-by-step explanation:
To find this, use the Pythagorean Theorem. Use 12 as the first leg, x as the second and 24 as the hypotenuse.
a^2 + b^2 = c^2
12^2 + b^2 = 24^2
144 + b^2 = 576
b^2 = 432
b = 20.78
Answer:
- 9/2 x 26/3 = -39
