Answer:
1.D) Procedure results in a binomial distribution.
2. B) Procedure results in a binomial distribution.
Step-by-step explanation:
The binomial distributions has following properties.
- There is always one of the two outcomes success or failure possible.
- The probability of p remains constant for all trials.
- The successive trials are all independent.
- The experiment is repeated for a fixed number of times.
If the experiment has the above properties it has binomial probability distribution.
In the given question both experiments have the above mentioned properties.
Both procedure result in binomial distribution.
Answer:
There are 15 letters, but if the two A's must always be together, that's the same as if they're just one letter, so our "base count" is 14! ; note that this way of counting means that we also don't need to worry about compensating for "double counting" identical permutations due to transposition of those A's, because we don't "count" both transpositions. However, that counting does "double count" equivalent permutations due to having two O's, two N's, and two T's, so we do need to compensate for that. Therefore the final answer is 14!/(23)=10,897,286,400
Answer: 30
Step-by-step explanation:
7(x+2)= 7x + 14
7x + 14 = 7x + 14
12×50=600
12×49=588
600-12=588
