So a box of 20 chocolates is divided between a group of people based on age
So the ratio for Sibusiso, Dorris, and Freddy is 2:3:5
Add these together, and you get 10
So to find how much each person gets, divide total amount of chocolates by total age
So (20÷10) = 2
So multiply each age term by 2 and you have your answer
(4:6:10)
So Sibusiso gets 4, Dorris gets 6 and Freddy gets 10
Answer:
a) P(2)=0.270
b) P(X>3)=0.605
c) P=0.410
Step-by-step explanation:
We know that customers arrive at a grocery store at an average of 2.1 per minute. We use the Poisson distribution:

a) In this case: 

Therefore, the probability is P(2)=0.270.
b) In this case: 

Therefore, the probability is P(X>3)=0.605.
c) We know that two customers came in in the first minute. That is why we calculate the probability of at least 5 customers entering the other 2 minutes.
In this case: 

Therefore, the probability is P=0.410.
BANK A:
5,000*0.03*5=750
BANK B:
5,000*0.025*6=750
They are the same
-10= 7X - 42
-10 + 42 = 7X
32 = 7X
X = 32/7
X = 4.57
