Answer: (D) 16%
Step-by-step explanation:
Binomial probability formula :-
, where n is the sample size , p is population proportion and P(x) is the probability of getting success in x trial.
Given : The proportion of students in College are near-sighted : p= 0.28
Sample size : n= 20
Then, the the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is given by :_

Hence, the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is closest to 16%.

Step:1
Area of smaller pizza,
...................................(1)
Where, r - Radius of small pizza
From given, 

r = 4 inches
Equation (1),

( ∵
=3.14 )
Square inches
Step:2
Area of smaller pizza,
...................................(1)
Where, r - Radius of small pizza
From given, 

r = 7.5 inches
Equation (1),

( ∵
=3.14 )
Square inches
Step:3
Cost of pizza per square meter,


= $ 0.1393 per square meter
× 

= $24.62
Result:

Answer:
They can select total 8 different furniture sets.
Step-by-step explanation:
Here given
The different choice of beds = 2
The different choice of dresser = 2
The different choice of desks = 2
And they need to choose 1 bed, 1 desk , 1 dresser
So, choice available for a desk = 2
Similarly, choice available for dresser = 2
and choice available for bed = 2
HENCE, THE TOTAL CHOICE OF PERMUTATION IS = 2 x 2 x 2 = 8
So they can select their furniture set in 8 different ways.
