Answer:
Correct option is b. Procedure results in a binomial distribution.
Step-by-step explanation:
Consider that <em>X</em> is Binomial random variable. The properties that are satisfied by <em>X</em> are:
- There are <em>n</em> independent trials.
- Each trial has only two outcomes: Success & Failure.
- Each trial has the same probability of success.
Suppose a roulette wheel is spun and the number of times the ball lands on '16' is observed.
If the random variable <em>X</em> is defined as the number of times the ball lands on '16', then the random variable <em>X</em> follows a Binomial distribution.
Because,
- Each spin is independent of each other
- Success: The ball lands on '16'
- Failure: The ball does not lands on '16'
- The probability of the ball landing on '16' is for each trial.
Thus, the correct option is b. Procedure results in a binomial distribution.
Answer:
D and yes
Step-by-step explanation:
+ 1 = -3 If we multiply both sides of the equation by 4 will will get the second equation
(4) + (4) 1 = (4) -3
x + 4 = -12 We solve this for x by subtracting 4 from both sides.
x = -16
Plug -7 into both equations and you will see that it is a solution
+ 1 = -3
+ 1 = -3
-4 + 1 = -3
-3 = -3
x + 4 = =12
-16 + 4 = -12
-12 - -12
