Adoctor has assigned the following chances to a medical procedure. 55% 24% 17% 4% full recovery condition improves no change condition worsens suppose the procedure is performed on 5 patients. assume that the procedure is independent for each patient. what is the probability that none of the patients will get worse

Step-by-step explanation:

Given: The probability of a patient will get worse =

The probability of a patient will not get worse =

Since the procedure is independent for each patient then the probability of 5 such events is the product of the probabilities of all 5 events .

Now, the the probability that none of the patients will get worse is given by :-

Hence, the the probability that none of the patients will get worse =

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
