# Probability of getting 2 odd numbers when rolling 2 fair dice? watch

1. I understand most of the formula to work these things out but i sometimes can't apply my knowledge. i tend to overthink things. can someone please explain the question to me and how i should go about figuring it out?
2. Assuming the dice have an even number of sides - they are d6s, d8s, or something - then each die's probability of rolling an odd number is 1/2, or 50%. The probability of both dice coming up odd is (1/2)(1/2) = 1/4, or 25%.
3. 1/4? Not a maths student here, but when you roll 2 dice there are 4 possibilities. Either you get and Odd Even dice, Even Odd dice, Even Even dice or Odd Odd dice. So, the probability of getting an odd odd dice is clearly 1/4...

i got the same answer as you guys, i know i had to use this formula: P(A and B)= P(a) * P(B)

but in this situation what is "A" and "B" is "A" odd or even or both or what? am i overthinking?

A is probability of first die landing on an odd number
B is probability of second die landing on an odd number
A and B is both dies landing on odd
A is probability of first die landing on an odd number
B is probability of second die landing on an odd number
A and B is both dies landing on odd
cheers mate! big help .
