36
Step-by-step explanation:
I did 24/2 (which is 12), which will give me 1/3 of the club. I added 12 to 24, and that means that there are a total of 36 people in the club
Answer:
Mean: 3 Mad: 1/3
Step-by-step explanation:
First we need to find out the numbers, so to get a mean of 3 we have to get to 9 ebcause there are 3 arrows.
- We have to make sure that the arrows are not too close to the center
- You can have decimals
2nd: Once you find the numbers which are 2.5, 3, and 3.5 you add them together and divide it by 3 to get 3 the mean
3rd: Find the MAD but adding .5 and .5 to get 1 then divide it by 3 and you get 1/3 as the MAD.
Hope this helps!

Answer:
0.0111% probability that he answers at least 10 questions correctly
Step-by-step explanation:
For each question, there are only two outcomes. Either it is answered correctly, or it is not. The probability of a question being answered correctly is independent from other questions. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
A multiple-choice examination has 15 questions, each with five answers, only one of which is correct.
This means that
What is the probability that he answers at least 10 questions correctly?
0.0111% probability that he answers at least 10 questions correctly
