Answer:
b. The number of digits in a randomly selected row until a 3 is found.
Explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.
2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.
Also, any random variable that meets certain conditions defined in a research study.
Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.
Answer:
PART A
- Red: 7/29
- Blue: 8/29
- Yellow: 5/29
- Green: 9/29
PART B
- Red or blue: 7/29 + 8/29 = 15/29
- Yellow or green: 5/29 + 9/29 = 14/29
- Blue or yellow or green: 8/29 + 5/29 + 9/29 = 22/29
Explanation:
In this case where the question is asking or <u>OR</u> and the events are <u>mutually exclusive</u> (Mutually exclusive meaning you can't attain two or three different colors in one pick), the compound probability is the sum of the probability of each component event (Probability of Red <u>OR</u> Blue = P(Red) + P(Blue) = 7/29 + 8/29 = 15/29)
Plug in -3 for x
the answer should be -6+-3-10
the answer is -19
