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".
Part a
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:
And for this case we want to find this probability:
We can use the probability mass function and we got
Part b
Let X the random variable of interest, on this case we now that:
And for this case we want to find this probability:
We can use the probability mass function and we got

Answer:
L = 17 m
Step-by-step explanation:
The formula for the volume of a rect. prism of length L, width W and height H is V = L*W*H. Here we are given certain values (W and H) and are asked to find the third value (L).
Solving V = L*W*H for L, we get
V
L = ----------
W*H
Subst. 2830.5 m³ for V, 18.5 m for W and 9 m for H. This results in:
2830.5 m³
L = -------------------- = 17 m
(18.5 m)(9 m)
The length of this prism is 17 m.
Step-by-step explanation: To find the next two terms in the pattern shown here, notice that we multiply by 2 to get from 4 to 8. Next we multiply 8 by 2 to get 16 and then we multiply by 2 to get from 16 to 32.
Continuing with the same pattern, we would next multiply 32 by 2 and would end with a product of 64. Finally we would multiply 64 by 2 and we would end up with a product of 128.
With this pattern, we can say that we will multiply 2 by each number that is in our pattern in order to get our next number in the pattern.
I did this test and failed. But when I reviewed it showed me the right answers... so here is the answer: C. There is no solution.
