X= 4.47213595 Is the answer to the question just round to the nearest 10th
Answer:
(a) 0.1666 (b) 0.5 (c) 0.166
Step-by-step explanation:
A die is rolled so sample space = { 1,2,3,4,5,6 } so n=6
(a) the number showing is four so expected value is only 4 so favorable outcomes {4}
so probability 
(b) the number showing an even number
so favorable outcomes= { 2,4 ,6 }
so probability 
(c) the number showing greater than 5 that is only {6}
so probability
