Answer:
that would not be correct
Step-by-step explanation:
its not correct because since its 5x squared thats going to be in a separate parenthesis for example it would look like this
i hope this helpsssss ...
1. P(getting all head)=
2. Event: getting all head can happen in only one way: HHH
3. n(Sample space) can be calculated by
a. counting, a good ways to organize counting is drawing a tree diagram, CHECK THE PICTURE
or
b. There are 2 possible outcomes each time we throw the dice so 2*2*2=8 is the total number of outcomes, that is the number of the sample space.
4. So finally P(getting all head)=
Answer: B 53/20
Step-by-step explanation:
.9+1.75 =2.65
2.65 = 53/20
Answer:
The normal distribution is explained for the solution of this question.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean = 25, Standard Deviation = 3.8
This means that
So
If P(X > k) = a
We have to find when Z has a pvalue of 1 - a.
If P(X < k) = a
We have to find when Z has a pvalue of a.
