Step 1
Given that,
New Covid-19 patients arrive at the emergency room in Sultan Qaboos Hospital at a mean arrival rate of 18.8 patients per hour.
Mean arrival rate in 15 minute can be calculated as follows:
λ=19.960×15
=4.7
Step 2
The probability that at least three new patients will arrive at the emergency room within a 15-minute interval can be calculated as follows:
P(X3)=1P(X<3)
=1[P(X=0)+P(X=1)+P(X=2)]
=1[e4.74.700!+e4.74.711!+e4.74.722!]
=1e4.7[1+4.7+11.045]
=1-0.1523
=0.8477
Thus, the probability that at least three new patients will arrive at the emergency room within a 15-minute interval is 0.8477.
