You are given 7 to 1 odds against rolling a sum of 6 with the roll of two fair dice, meaning you win $7 if you succeed and you lose $1 if you fail. Find the expected value (to you) of the game.
Answers
Answer:
The expected value of the game is $0.33.
Step-by-step explanation:
There are N = 36 outcomes of rolling two 6-sided fair dice.
The sample for the sum of two numbers to be 7 is:
S = {(1, 6), (2, 5), (3, 4), (4, 3), (5, 2) and (6, 1)}
n (S) = 6
It is provided that there is a 7 to 1 odds against rolling a sum of 6 with the roll of two fair dice.
That is, you win $7 if you succeed and you lose $1 if you fail.
Compute the expected value of the game as follows:
Thus, the expected value of the game is $0.33.

Answer:
Length = x+13=6+13=19units
Step-by-step explanation:
P = 2(l +w)
Let width be x
Length = x + 13
P = 38
38 = 2(x + 13 + x)
38 = 2(2x + 13)
38 = 2x + 26
2x = 38 - 26
2x = 12
x = 12/2
x = 6unit
Width = 6units
Length = x + 13 = 6+13 = 19units

Answer:
93.32% probability that the weight will be less than 4356 grams.
Step-by-step explanation:
Problems of normally distributed samples are 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.
In this problem, we have that:
If a newborn baby boy born at the local hospital is randomly selected, find the probability that the weight will be less than 4356 grams.
This is the pvalue of Z when X = 4356. So
has a pvalue of 0.9332
93.32% probability that the weight will be less than 4356 grams.
