Answer:
0.06
Step-by-step explanation:
Given that :
Average number of road accident (n) = 11
Probability of observing exactly 7 accident o. The stretch of road next year
Poisson random variable (k) = 7
Using the poisson distribution formula :
P(x = k) = (n^k * e^-n) / k!
P(x = 7) = (11^7 × e^-11) / 7!
P(x = 7) = (19487171 × 0.0000167017) / 5040
P(x = 7) = 325.4688838907 / 5040
P(x = 7) = 0.0645771
= 0.06
