See below

Explanation:

By Laplace rule we have P(A)=favourable cases / total cases

We supose a balanced dice with equal probability in all faces=#1/6#

#P(4or5)=2/6=1/3# Favourable cases #{4,5}# cardinal=2

#P(1 or dot2)=4/6=2/3# Favourable cases #{1,2,4,6}# cardinal=4

#P(3 or even)=4/6=2/3# Favourable cases #{3,2,4,6}#

#P(6 or >3)=3/6=1/2# Favourable cases #{4,5,6}#
