Answer:option B is the correct answer
Step-by-step explanation:
The formula for poisson distribution is expressed as
P(x = r) = (e^- µ × µ^r)/r!
Where
µ represents the mean of the theoretical distribution.
r represents the number of successes of the event.
From the information given,
µ = 2.19
For the probability of no accidents on this section of highway during one day period, r = 0
Therefore,
P(x = 0) = (e^- 2.19 × 2.19^0)/0!
P(x = 0) = (e^- 2.19 × 1)/1
P(x = 0) = 0.112
