Answer:
5/12
Step-by-step explanation:
There is a total of 12 bags, 5 of which are bbq
P ( bbq) = number of bbq/ total
= 5/12
M in (-oo:+oo)
m+11 = (1/4)*m-(2*m) // - (1/4)*m-(2*m)
m-((1/4)*m)+2*m+11 = 0
m+(-1/4)*m+2*m+11 = 0
11/4*m+11 = 0 // - 11
11/4*m = -11 // : 11/4
m = -11/11/4
m = -4
m = -4
Answer: a) 0.8413, b) 0.9987.
Step-by-step explanation:
Since we have given that
Mean = 3 pounds
Standard deviation = 0.25 pounds
n = 28 bricks
So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?
b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?
Hence, a) 0.8413, b) 0.9987.
