Answer:
Sure Amaya , the grouping is the parenthesis, right?
Step-by-step explanation:
so just add up.. the things outside of the parenthesis
- * 4
so exponents come first in the order of what to do... right?
=16 okay , got that part, the next part is
16 * 4 = 64 okay got that part, now
- 64 is what is subtracted from the grouping , got it?
The mean exists at 3 and the standard deviation exists 0.87.
Using the binomial distribution, it exists seen that the mean and the standard deviation of X exist given as follows:
The expected value of the binomial distribution exists:
The standard deviation of the binomial distribution exists:
In this problem, the proportion and the sample size exist given as follows:
p = 0.75
n = 4
Therefore, the mean and the standard deviation exist given by:
The mean exists at 3 and the standard deviation exists 0.87.
