A. what is the probability that a service time is less than or equal to one minute (to 4 decimals)?

a. What is the probability that a service time is less than or equal to one minute (to 4 decimals)?"

The exponential distribution probability is given by the formula:

where: 

λ = average in unit time = 1/2.2 = 0.45 services per minute       

t = time requested = 1 minute

p(T ≤ 1) = 0.3624

Hence, the probability that a service time is less than or equal to one minute is p = 0.3624, which means 36.24%.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
