Answer:
b = 48
Step-by-step explanation:
b / 4 = 12
b / 4 * 4 = 12 * 4
b = 48
2w+4=35
w=15.5
I hoped i helped
the answer is 1/8 because since one toss would be 1/2 then 1/2 * 1/2 *1/2= 1/8
Answer:
The probability that the instrument does not fail in an 8-hour shift is 
The probability of at least 1 failure in a 24-hour day is 
Step-by-step explanation:
The probability distribution of a Poisson random variable X representing the number of successes occurring in a given time interval or a specified region of space is given by the formula:

Let X be the number of failures of a testing instrument.
We know that the mean
failures per hour.
(a) To find the probability that the instrument does not fail in an 8-hour shift, you need to:
For an 8-hour shift, the mean is 

(b) To find the probability of at least 1 failure in a 24-hour day, you need to:
For a 24-hour day, the mean is
