Three divided by five equals 0.5
Well really all you have to do is divide 3450/3/4= which gives a decimal so your answer is 287.5
Answer:
260 minutes > 4.25 hours
Step-by-step explanation:
1h=60 min.
0.25 h=¼h=¼*60min=15min.
4.25h=4h+0.25h=60*4+15min=240+15=255min
260>255
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)](https://tex.z-dn.net/?f=Y%20-%20Bin%20%28n%2Cp%29)
Given , ![n = 4 , p = 0.75 , q = 1 - p = 0.25](https://tex.z-dn.net/?f=n%20%3D%204%20%2C%20p%20%3D%200.75%20%2C%20%20q%20%3D%201%20-%20p%20%3D%20%200.25)
![P (Y = 3) = \left(\begin{array}{ccc}4\\3\\\end{array}\right) (0.75)^{2}(0.25)^{4-3} \\ = 0.21094\\\\](https://tex.z-dn.net/?f=P%20%28Y%20%3D%203%29%20%3D%20%5Cleft%28%5Cbegin%7Barray%7D%7Bccc%7D4%5C%5C3%5C%5C%5Cend%7Barray%7D%5Cright%29%20%20%280.75%29%5E%7B2%7D%280.25%29%5E%7B4-3%7D%20%20%5C%5C%20%20%20%20%20%20%20%20%20%20%20%20%20%3D%20%200.21094%5C%5C%5C%5C)
The probability that the surgery is successful on exactly 3 patients is 0.21094
