Answer:
true
Step-by-step explanation:
since a is smaller than or equal to 6 then it should be smaller than or equal to a bigger value like 12
Answer:
35/132
Step-by-step explanation:
The probability of selecting a boy for president is 7/12, the ratio of the number of boys to the number of candidates. Then the probability of selecting a girl for vice president is 5/11, the ratio of the number of girls to the remaining number of candidates. The joint probability is ...
(7/12)(5/11) = 35/132 . . . P(b=P&g=VP)
__
We can also look at this another way.
The number of ways two candidates can be selected from 12 is 12P2 = 132. The number of ways that the first can be a boy and the second can be a girl is (7)(5) = 35. Then the probability of a (BG) pair from the 12 candidates is 35/132.

<em>Additional comment</em>
These numbers assume that selection is random and all possibilities are equally-likely. That is unlikely to be the case in an election.
Answer:
-16
Step-by-step explanation:
You pick only one letter, so the possible outcomes are:
A,C,O,M,D,T, I, N
if you need to probability of each outcome:
A: 2/13 (there are 2 As and a total of 13 letters)
C: 2/13
O: 3/13
ans so on.
use your calculator to change each fraction to a decimal if needed.
