Answer:

The number of the students is 20.

Explanation:

Total number of students in the speech contest = 90

Number of students that gave their speeches yesterday =
(2)/(3) of 90

=
(2)/(3) x 90

= 60

Number of remaining students who have not given their speeches after the first day = 90 - 60

= 30

Number of students that gave their speeches today =
(1)/(3) of 30

=
(1)/(3) x 30

= 10

Number of students that have not given their speeches = 30 - 10

= 20

Thus, 20 students have not given their speeches.
