Answer:
a) uniform
b) 1/2
c) 1/1000
Step-by-step explanation:
a) "numbers with equal probability" have a uniform distribution.
__
b) Even numbers make up 1/2 of all numbers.
__
c) There are ten such numbers in the range, so the probability is ...
10/10000 = 1/1000
16% = 0.16
1/6 = 0.16666
1.6x10^6 = 1600000
0.166 = 0.166
order from greatest to least:
1.6x10^6, 1/6, 0.166, 16%
Answer is D
No, because element b has 2 correspondents.
