Step-by-step explanation:
I guess you just slove the exponent can I see the actual question
69.58. 19.8x3=59.64 and 19.88/2 is 9.94. 59.64+9.94=69.58
Answer:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
The probability of finding a value higher than x is:
Average repair time of 2 hours
This means that
What is the probability that the repair time takes between 2 to 4 hours
More than 2:
Less than 4:
Between two and four:
0.4968 = 49.68% probability that the repair time takes between 2 to 4 hours
Answer:
no
