Answer:
[See Below]
Step-by-step explanation:
First you'll solve the parenthesis part:
* 12 - 3 = 9
Then Solve the exponents:
* 4^4 = 256 (4 x 4 x 4 x 4)
* 3^3 = 27 (3 x 3 x 3)
Rewrite:
* 256 - 27 x 9 - 20
Multiply:
* 27 x 9 = 243
Subtract:
* 256 - 243 = 13
* 13 - 20 = -7
So the answer would be B, -7

Answer:
The required probability is 0.0155.
Step-by-step explanation:
We are given that the one-year survival rate for pancreatic cancer is 20%.
Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 12 people
r = number of success = 6 survived
p = probability of success which in our question is probability of
one-year survival rate for pancreatic cancer, i.e; p = 20%
Let X = <u><em>Number of people survived one year</em></u>
So, X ~ Binom(n = 12 , p = 0.20)
Now, the probability that 6 survived one year is given by = P(X = 6)
P(X = 6) =
=
= <u>0.0155</u>
