sorry im real bad at probability.
a single die is rolled. find the probabilities:
a) P(odd numbers greater than 1)
b) P(number less than 5)
c) P(the number 3 or 7)
i got
a) 1/3 b) 1/2 c) 1/6
is that right please help.

b) is wrong; the others are OK.
There are 4 numbers (out of 6 possible) that are less than 5.
