Answer:
a)0.2240
b)0.5768
Step-by-step explanation:
Given:
µ=3
Poison probability is given by :

a) Evaluating at k=3

b)Evaluating at k=0,1,2:



Use complement rule:
P(x≥3)= 1 - f(0) - f(1) - f(2)= 1- 0.0498 - 0.1494 - 0.2240 =0.5768
Answer:
9.19 mi. is the distance between Bank and Grocery store.
Step-by-step explanation:
As we know in a given triangle with sides a, b, c which are the opposite sides of ∠A, ∠B, ∠C, follow the property

Now we apply this property in the given triangle.
Let the distance between Grocery store and Bank = x mi



So the answer is 9.19 mi.
Yea divide 4/11 and you will get 0.36363636 infinitely
