Step-by-step explanation:
Given that two fair dice, one blue and one red, are tossed, and the up face on each die is recorded.
a) P(E) = P(the difference of the numbers is 3 or more}
Favourable events are (1,4) (1,5)(1,6) (2,5) (2,6) (3,6) (4,1) (5,1) (5,2) (6,1) (6,2)(6,3)
P(E) =
b)P(F)
Favourable events for F = (1,1) (2,2)...(6,6)
P(F) =
c) P(EF)
There is no common element between E and F
P(EF) =0
