A student committee of 4 is formed by randomly drawing people (without replacement) from a collection of 4 sophomores, 4 juniors and 3 seniors. What is the probability the committee thus formed will have at least one representative from all three groups of students?

Answers

Answer: 0.04848

Step-by-step explanation:

Given : There are 4 sophomores, 4 juniors and 3 seniors.

Total choices = 4+4+3 = 11

Number of people needed to be chosen for committee = 4

Number of ways to select 3 people out of 11 (without replacement)=  ^(11)P_4

=(11!)/((11-4)!)\ \ \ \ [^nP_r=(n!)/((n-r)!)]

=(11*10*9*8*7!)/(7!)\n\n= 7920

 

 

Number of ways to select at least one representative from all three groups of students =  ^4P_2* ^4P_1* ^3P_1+^4P_1* ^4P_2* ^3P_1+^4P_1* ^4P_1* ^3P_2

=(4!)/(2!)*4*3+4(4!)/(2!)*3+4*4*(3!)/(2!)\n\n= 144+144+96=384

Required probability = (384)/(7920)=0.04848

Hence, the probability the committee thus formed will have at least one representative from all three groups of students = 0.04848

Answer:

Thor is the best deal.

Step-by-step explanation:

Thor is $10.35, Lemon is $11.73, Patrick is $14.66, and Sarah is $16.63.

For Thor, multiply $1.15(2)=$2.30. Then multiply $1.15(7)=$8.05. Add these together to get $10.35.

For Lemon, multiply 17($1.15)=$19.55. Then subtract by $7.82 to get $11.73.

For Patrick, use the equation we already did 17($1.15) and subtract $4.89 from it to get $14.66.

Last, For Sarah multiply our $19.55 (.15) to find 15% and get 2.934. Then subtract $19.56 - 2.934 to get $16.626. Round to $16.63.

Hope this helped!
