Answer:
0.4546
Step-by-step explanation:
nCr = n!/(n-r)!r!
Number of ways of selecting the four defective voltage regulators from 12 = 12C4 = 12!/(12-4)!4! = 12!/8!4! = (12 *11*10*9)/(4*3*2*1)
12C4 = 495 ways
Number of ways of selecting 2 defectives from line 1 = 6C2 * 6C2
6C2 = 6!/(6-2)!2! = 6!/4!2! = (6*5)/(2*1) = 15
6C2 * 6C2 = 15*15 = 225 ways
Probability = Number of possible outcomes/ Number of total outcomes
Probability that exactly 2 of the defective regulators came from line 1 = 225/40.95 = 0.4546

The diameter of the circle is 56 cm.
Step-by-step explanation:
Given : The area of the circle is 2464 cm square.
To find : The diameter of the circle?
Solution :
The area of the circle is defined as
Where, A=2464 cm² is the area,
r is the radius
Substituting the values,
Radius of the circle is 28 cm.
The diameter of the circle is
Therefore, The diameter of the circle is 56 cm.
