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:
Jack: 4 x 6 = 24
Jill: 5.4 x 10 = 54
Step-by-step explanation:
Jack:
5 + 1 = 6
24 ÷ 6 = 4
4 = $4 per item
Jill:
6 + 4 = 10
54 ÷ 10 = 5.4
5.4 = $5.4
B: 11
N: 5
