Anew surgical procedure is said to be successful 60% of the time. suppose the operation is performed nine times and the results are assumed to be independent of one another. what are the probabilities of these events? (round your answers to three decimal places.)

The probabilities are:

Step-by-step explanation:

Lets call X the total number of success. X counts the number of success from the same experiment repeated 9 times with a probability of success of 0.6 and one experiment independent of the other. Therefore X has Binomial distribution, X ≈ Bi(9,0.6).

The range of X is {0,1,2,3,4,5,6,7,8,9} and the probability of X being equal to a value k in its range is the number  given by

Thus,

I hope that works for you!

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
