Hello. I will be needing some assistance in this probability question as I find it hard to understand the chapter. Hope you can provide solutions to this question.
Question 2
a) In a regional city, two lawn companies fertilise lawns during the summer. Company A has 72% of the market. Thirty per cent of the lawns fertilised by Company A could be rated as very healthy one month after the service. Company B has the other 28% of the market. Twenty per cent of the lawns fertilised by Company B could be rated as very healthy one month after the service. A lawn that has been fertilised by one of these companies within the last month is selected randomly and is rated as very healthy.
i) What is the revised probability that Company A fertilised the lawn?
ii) What is the corresponding probability that Company B fertilised the lawn?
b) Of 250 employees of a company, a total of 130 are full-time employees. The remain-der are part-time employees. There are 150 males working for this company, 85 of whom are full-time employees. What is the probability that an employee chosen at random:
i) is a part-time employee?
ii) is female and a full-time employee?
iii) is a full-time employee, given that the employee is female?
iv) is a female, given that the employee is full-time?
v) Are the events employee chosen at random is female” and employee chosen at random is full-time” statistically independent?
c) Let P (A[B) = 0:9, P (A) = 0:5 and P (B j A) = 0:4. Calculate P (B) and P (A j B). Are A and B independent? Are A and B disjoint? Justify your answers.
d) Let P (A) = 0:2, P (A [ B) = 0:6, and suppose the events A and B are independent. Calculate P (B).
e) Let P (A) = 0:6, P (A j B) = 0:6 and P (A[B) = 0:8. Calculate P (B) and P (AB). Are A and B independent? Justify your answer.
f) A toy manufacturer buys pre-assembled robotic arms from three different suppliers 50% of the total order comes from Supplier 1, 30% of the total order comes from Supplier 2, and the remaining 20% from Supplier 3. Past data shows that the quality control standards of the three suppliers are different. Two percent of the arms produced by Supplier 1 are defective, while Suppliers 2 and 3 produce defective arms at the rates of 3% and 4% respectively.
Let Si be the event that a given arm comes from Supplier i, i = 1; 2; 3 and let D be the event that a given arm is defective.
i) Draw a tree diagram that models this situation.
ii) What proportion of the arms in the manufacturer’s inventory are non-defective?
iii) If an arm is found to be defective, what is the probability that it came from Supplier 1? Give your answer to 4 decimal places.

hello,
I was wondering if I could have some help with this problem; there is a list of properties on the natural numbers that the problem asks us to reference and use at our own discretion. However, I’m not entirely sure which properties I should use to prove the following by induction, after having shown the base case. I’m having most trouble showing the inductive case, i.e. the n+1 case.
Let f : N → N be a function. Suppose that f(n)< f(n+1) for all n∈N. Prove that f(n)≥n for all n∈N.
Thank you for your help
All the best
