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".
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:
Solution to the problem
We want to find this probability:
And we can use the pmf and we got:
A function assigns the values. The table can be represented by a function.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
No, the number of videos kept on Ruby's friends' phones cannot be expressed as a function of the number of songs. A function produces a distinct result for each input. When the input is 125, we get two distinct results. As a result, the table does not represent a function.
Hence, the table can be represented by a function.

9 nickles and 12 dimes.
This would equal 1.65
Answer:
9/40 of his salary
Step-by-step explanation:
You may want to add the fractions first or subtract one and then the other. I am going to add them first.
(3/8) + (2/5)
(15/40) + (16/40) = (31/40)
1 whole salary (40/40) - (31/40) = (9/40)
Since 9 and 40 have no common factors, the simplified answer is 9/40.
X/3-17=80
x/3=97
x=291
291-97=194
194-97=97
Emily had $97 more than Sara.
