Question

Calculate the probability that both number of dices are less than five

Answer 1

possible variants:

$(1,1),(1,2),(2,1),(2,2),(1,3),(1,4),(3,1),(4,1),(2,3),(3,2),(3,3),$

$(2,4),(4,2),(3,4),(4,3),(4,4)$

number of possible variants:

$n=16$

total number of variants:

$N=36$

probability that both number of dices are less than five:

$P=n/N=16/36=4/9$
