Answer:
b) Complement of spinning any number less than 3 is Spinning 3 or 4.
Step-by-step explanation:
COMPLIMENT of any Set A is the set of all the elements which are in the sample space but NOT IN SET A.
Here, Event E = Spinning a spinner with 4 parts and getting a number less than 3.
Here, Sample Space = {1,2,3,4}
Also, as outcomes is LESS THAN 3, ⇒ E = {1 ,2}
Now, Compliment E = Sample Space - { Elements in set E}
= {1,2,3,4} - {1 ,2}
or, E' = { 3,4}
Hence, complement of spinning any number less than 3 is Spinning 3 or 4.
A = pi x r^2
A = pi x 8^2
A = pi x 64
A = 201.061..
A = 201cm^2 (3sf)
