Not really the same.
Adaptive BECN will RESPOND TO congestion notification. Some other device is
setting the BECN.
Normally, WRED will drop packets based on the mark probability denominator
and the min / max threshold.
ECN with WRED is an addition to WRED that marks the ECN bits in the packets
instead of dropping.
What did the task ask you to do? Were you asked to RESPOND to BECN being
set?
WRED - Explicit Congestion Notification (ECN) -

question regarding the actual solution and what i came up with.
the actual solution guide had the following
policy-map X
class class-default
fair-queue
random-detect
random-detect dscp based
random-detect ecn
int s0/0
service policy X out
my solution was:
int s0/0
fair-queue
random-detect
random-detect dscp-based
frame-relay class frts501
map-class frame-relay frts501
frame-relay adaptive becn
are the 2 policies comparable? the seem to be to me anyhow!
