You roll 1 red and 1 white dice. What is the probability that the number on the red die is larger than the number on the white die?
can anyone help me?:(

its simple use a 2 way table and look at where the red is larger than the white
there are 6 x 6 pairings
just tick where red is greater than white
I'll let you finish it
it's 1*2*3*4*5 if you need explanation, I'll explain.

That's not correct @Yttrium . And explanations are always more important that just giving answers.
@campbell_st has a good method - as you can see, there are 36 possible outcomes in the sample space (6 for the red die, and for each of those 6 possible outcomes there are 6 possible outcomes for the white die).
So now you just need to determine, in how many of those rolls is the number on the red die is larger than the number on the white die?
You can use a table method as above, or just think through the possibilities:
If white rolls a 1, there are 5 possible rolls on red that are larger.
If white rolls a 2 there are 4 possible rolls on red that are larger, so now we have 5+4=9.
...and so on.... through all the possible rolls on white.
c) Explain pigeon hole principle. Using this principle show that in any
group of 36 people, we can always find 6 people who were born on the
same day of week.
