All six different robots have to be assigned to three different
tasks. Three (3) robots have wheels only (Type I) and the other
three (3) having legs only (Type II). Individual performance of the
robots varies for a pending task due to the differences in failure
rates, reliability and adaptability. Answer the following
questions
: 1) If we plan to assign one (1) robot to Task 1, two (2)
robots to Task 2, and three (3) to Task 3, in...

and one of 4 suits, ♡,♢,♠,♣♡,♢,♠,♣
A hand called a royal flush consists of cards of
the values 10,J,Q,K,A10,J,Q,K,A, all from the same suit. For
instance, a royal flush with hearts would be
