0.21094 is the probability that the surgery is successful on exactly 3 patients.

<h3>What is probability?</h3>

It is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

According to the given question,

Let Y = The number of patients who respond yes: Y - Bin (n,p)

Given , n = 4 , p = 0.75 ,  q = 1 - p =  0.25

P (Y = 3) = \left(\begin{array}{ccc}4\\3\\\end{array}\right)  (0.75)^{2}(0.25)^{4-3}  \\             =  0.21094\\\\

The probability that the surgery is successful on exactly 3 patients is 0.21094

A 5-pound bag of apples cost $3.50. Use that rate, to complete the table to identify equivalent ratios, and then answer the ques
STALIN [3.7K]
Set up a proportion. 3.50 over 5 = x over 1 (x is what we are trying to find= the cost of 1 lb of apples)
Use cross products and multiply 3.50 by 1 to get 3.50 and then divide that by 5 to get 0.7.

So the apple cost 0.7 or seventy cents per pound.

Check: 0.7*5=3.5

That is correct!

Hope this helps!
