Answer:
19/25.
Step-by-step explanation:
The total possible number of combinations of 2 cards from the 2 piles = 5*5 = 25.
Possible ways to get sum of 12 or more =
4,8 5,7 5,8 6,6 6,7 6,8 = 6 ways.
So the number of ways to get sum of < 12 = 25 - 6 = 19.
So the required probability = 19/25.

Answer:
a)x1 = -2, x2= 2
b) x= -1
Step-by-step explanation:
For a 99% confidence interval for
μ based on a simple random sample.
Part (a):
Is it correct to say that
the probability that μ is in the specified interval is 99%?
Explain.
No. The probability that μ falls inside the interval is 0 or 1.
Rather we say that we are 99% confident that μ will fall inside the interval.
Part B:
Is it correct to say that in the long run, if you computed many,
many confidence intervals using the prescribed method, about 99% of
such intervals would contain μ?
Yes. 99% of intervals constructed using this method will capture
the population mean μ.
