The answer is (2,5) because then there would be two coordinates
Answer:
Binomial, with 
Step-by-step explanation:
For each student, there are only two possible outcomes, either they own a cellphone, or they do not. The probability of a student in the sample owning a cellphone is independent of whether other students own a cellphone or not. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution:
Probability of exactly x sucesses on n repeated trials, with p probability.
90% of students now own a cell phone.
This means that 
Fifteen students are to be selected at random from a large university.
This means that 
What is the appropriate distribution for X?
Binomial, with 
Answer:
Maria answers <u>85%</u> of the questions correctly
Step-by-step explanation:
Maria had a test with 20 questions
if 17 are correct,
20 questions : 100%
17 questions : ?%
she was 85% right<em>

Each die has six numbers, the total number of possible combinations is 6 * 6 = 36
The combinations in which you can get a sum of 5 are: 1 &4, 2 & 3, 4 &1, 3 &2
There are 4 different combinations of getting a sum of 5.
The probability would be 4/36, which reduces to 1/9
