Explanation / Answer

(1) (A) a sample point

It is a single possible observed value of a variable or a member of the sample space of an experiment

It is the most basic outcome of an experiment.

(2) (C) the sample space

It is the collection of all its sample points for an experiment.

(3) Experimental outcomes

=4 outcomes * 5 outcomes * 6 outcomes= 120 outcomes total

option (B) 120 is correct

(4)

Selection of 2 letter from 5 different letter

=5C2 = (5!)/(3!*2!) = 10 ways  

Option (D) is correct
