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:
<h2> 105 points</h2>
Step-by-step explanation:
1%=0.01 ⇒ 40% = 40•0.01 = 0.4
x - total of team points
40%x = 42
0.4x = 42
÷4 ÷4
0.1x = 10.5
•10 •10
x = 105
Suppose the spot rates for 1 and 2 years are s1=6.3% and s2=6.9% with annual compounding. Recall that in this course interest rates are always quoted on an annual basis unless otherwise specified. What is the discount rate d(0,2)? Please submit your answer rounded to three decimal places. So, for example, if your answer is 0:4567 then you should submit an answer of 0:457.
So you take the lowest and highest values of each set and subtract the lowest value from the highest one (to calculate the range).
A. Range is 17
B. Range is 22
C. Range is 23
D. Range is 24
Therefore D’s set of data has a range with the greatest difference
