Given information

Number of persons in democratic party year of 2014is 20.

Number of persons in democratic party year of2016is10.

Calculation for probability

Randomly selected member of US Senate is Democrat.

In November 2016,

Number of person in democratic party is localid="1649668748251" 10.

Probability=NoofpersonsTotalnoofpersons

Total no of persons in democratic party is equal to sum of persons in November 2014and2016.

So,

Total no of persons=20+10

=30

Thus,

P(Democraticparty)=1030

=13
