Answer:
1
Step-by-step explanation:
(1/2)(2/1)=2/2=1
In the middle of 3 and 4 but a little more to the 3
No, this is not normal
This is a binomial distribution. Use BINS to determine if this is binomial.
B - binary?
I - independent?
N - number of trials
S - probability of success
B - yes, 3 or not a 3
I - yes, past rolls do not impact future rolls
N - 20 trials
S - prob success 1/6
Use binompdf on your calculator to find out the probability. To access, 2nd —> vars —> binompdf
Binompdf(20 (trials), 1/6 (p), 11 (x)) = 8.97x10^-5
The probability to roll a 3 11 times is .0000897. The chances are very low, making this not normal.
The expression given is
![\frac{1}{8}+\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D%2B%5Cfrac%7B1%7D%7B6%7D)
The sum of the expression will be,
![\frac{1}{8}+\frac{1}{6}=\frac{6+8}{48}=\frac{14}{48}=\frac{7}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D%2B%5Cfrac%7B1%7D%7B6%7D%3D%5Cfrac%7B6%2B8%7D%7B48%7D%3D%5Cfrac%7B14%7D%7B48%7D%3D%5Cfrac%7B7%7D%7B24%7D)
The sum will be
X would equal 3 and y would equal 7
