Person x rolls a die three times. What is the probability that her second and third rolls are both larger than her first roll?

(ex 5:6:6) (not ex:5:5:6)

also

the result of her second roll is greater than that of her first roll and the result of her third roll is greater than the second?

(ex: 4:5:6) (not ex: 5:6:6

thanks for your help

part a:

first roll she can roll 1-5, second roll she can roll 2-6, third roll she can roll 2-6.

thats all i've got.
