Answer:1/2
Step-by-step explanation
Probability (P) is given as the ratio of number of outcome (N) to total possible outcome (NP). That is
P =N/Np
On a dice, we have (1,2,3,4,5 and 6 faces)
Np = Total number of possible outcome
=6
Faces less than 4 = (1,2, and 3 faces)
N = 3
Therbefore, P = N/NP =3/6 =1/2
Answer = 1/2
