Answer:
Step-by-step explanation:
Data provided in the question:
Number of cups of tea offered = 3
Number of cups marked = 9
Number of cups tasted by each = 4
Now,
The probability that a contestant does not taste all of the samples
= contestant tastes only 2 samples of tea
= 
C₆⁴ = number of ways to choose 4 cups out of 6 cups of two samples
C₃² = number of ways to choose which 2 samples will be tasted
[ as 2 samples × 3 cups each = 6 cups ]
C₉⁴ = Number of ways to choose 4 cups out of 9
=
Hence,
the correct answer is option (B) 5/14

Answer:
Each of them will get 3.375 inches of cookie.
Step-by-step explanation:
Rasputen and his three buddies are splitting a giant 18 inches cookie.
But they notice that 
th of it is missing.
So, the actual length of the cookie is ![18[1-\frac{1}{4} ]=18 \times \frac{3}{4}=13.5](https://tex.z-dn.net/?f=18%5B1-%5Cfrac%7B1%7D%7B4%7D%20%5D%3D18%20%5Ctimes%20%5Cfrac%7B3%7D%7B4%7D%3D13.5)
inches.
If all the four of them get the same amount of the giant cookie then each of them will get 
inches of cookie. (Answer)
Part A
Use the binomial probability distribution formula.
p = 0.54 = probability of getting a purple marble
n = 5 = sample size
x = 2 = number of purple we want to get
The 
portion is from the nCr combination formula. The exclamation marks indicate a factorial.
Alternatively, you could use Pascal's Triangle for that portion.
<h3>Answer: 0.283831776</h3>
This decimal value is exact. Round it however you need to.
============================================================
Part B
To find the expected value, aka the mean, we multiply the sample size and probability of getting a purple marble on any single selection.
n*p = 5*0.54 = 2.7
<h3>Answer: 2.7</h3>
