PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer 1

Answer:  C & D

Step-by-step explanation:

A binomial experiment must satisfy ALL four of the following:

1.  A fixed number of trials
2.  Each trial is independent of the others
3.  There are only two outcomes (Success & Fail)
4.  The probability of each outcome remains constant from trial to trial.

A) When the spinner is spun three times, X is the sum of the numbers the spinner lands on.

  → #3 is not satisfied  (#4 is also not satisfied)

B) When the spinner is spun multiple times ...

    → #1 is not satisfied

C)  When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.

    → Satisfies ALL FOUR

1.  A fixed number of trials = 4
2.  Each trial is independent of the others = each spin is separate
3.  There are only two outcomes = Not Odd & Odd
4.  The probability of each outcome remains constant from trial to trial = P(X = not odd) = 0.50 for each spin

D) When the spinner is spun five times, X is the number of times the spinner lands on 1.

   → Satisfies ALL FOUR

1.  A fixed number of trials = 5
2.  Each trial is independent of the others = each spin is separate
3.  There are only two outcomes = 1 & Not 1
4.  The probability of each outcome remains constant from trial to trial = P(X = 1) = 0.17 for each spin
