Answer:
The speed of a rhino is 41 feet/second.
Step-by-step explanation:
A rhino can run at speed of about 28 miles per hour.
In one hour a rhino can run = 28 miles
As we know 1 hour = 3600 seconds
1 mile = 5280 feet
28 miles = 5280 × 28 = 147,840 feet
Therefore, we can say in 3600 seconds a rhino can run = 147,840 miles
So the speed per second = = 41.06 ≈ 41 feet
The speed of a rhino is 41 feet/second.

Answer:
The probability that occurrence of 8 in ten minutes is 0.0771.
Step-by-step explanation:
Poisson Distribution:
A discrete random variable X having the enumerable set {0,1,2,.....} as the spectrum, is said to have Poisson distribution with parameter (>0), if the p.m.f is given by
for x=0,1,2,...
= 0, elsewhere
The mean number of occurrences in ten minutes is 5.3.
Here = 5.3 and x= 8
=0.0771
The probability that occurrence of 8 in ten minutes is 0.0771.
