Because back when cowboys were around, math was not necessarily a huge factor in a human's daily lifestyle.
Lol, you're welcome ;)
After she retrieves either a black or a white sock she has a one in 3 chance of retrieving the same coloured sock.
So with 2 socks retrieved we cant be sure she has 2 that match.
Picking a third sock:-
If the first 2 match then she will have a pair.
If the first 2 were different then whatever one she picks there must be a match
So the answer is 3 socks from the drawer.
The missing step is simply 2x=-6. You just subtract the eight.
Answer:
The probability is 0.0478 that the mean weight will exceed 8.2 ounces.
Step-by-step explanation:
1. Find the mean and standard deviation of the sampling distribution of x.
µx = µ = 8
σₓ = σ/√n = 0.6/√25 = 0.12
2. Since we know the meat on a Subbies foot-long has a sampling distribution of N(8, 0.12), we can use Normal probability calculations:
normalcdf(8.2, 9999, 8, 0.12) = 0.0478
Hope this helped!
