What is the number to put in fraction form?
Answer:
a)
b)
And we can use the complement rule and we got:
And replacing we got:
c)
d)
e)

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part a
We want this probability:
And using the probability mas function we got:
Part b
We want this probability:
And we can use the complement rule and we got:
And replacing we got:
Part c
We want this probability:
Part d
the expected value is given by:
Part e
The standard deviation is given by:
To use one as a benchmark fraction in order to compare 6/5 and 5/6, you will use fractions that are equal to one with denominators of 5 and 6.
Ex: to compare 6/5 to one, you will write 5/5 for one whole. 6/5 is greater than 5/5.
Ex: to compare 5/6 to one, you will write 6/6 for one whole. 5/6 is less than 6/6.
This means that 6/5 is greater than 5/6 because 6/5 is greater than 1 and 5/6 is less than 1.
Answer: because you would be naked for 1 and 2 they protect you?
