Two six sided dice (one is red, one is green) are rolled. Determined the following probabilities:
1)
What is the probability that the red die is even and the green die is odd? That is, P(R=even∩G=odd)
2)What is the probability that the sum of the red and green values is 8 .
3) What is the probability that the sum of the red and green values is <7 ? That is, P(R+G<7).
4) What is the probability that red value is ≤ green value? That is, P(R≤G)
5) What is the probability that red value ≤ green and the green value is <6 ? That is, P(R≤G∩G<6)

Best ResponseYou've already chosen the best response.0ok for number 1 do you know that if you have two independent probabilities you multiply them to find their combined probability?

Best ResponseYou've already chosen the best response.0so the P(even dice roll)=.5 and P(odd dice roll)=.5 so .5•.5=.25

Best ResponseYou've already chosen the best response.0I don't quite understand your fraction for part 4. 7/6? So you're saying the red die will be less than the green die over 100% of the time?

Best ResponseYou've already chosen the best response.0i just simplify the number 16/36

Best ResponseYou've already chosen the best response.0Which does not simplify to 7/6... but anyway I think maybe you missed a few, hmm If a 1 is rolled on the red die, and we want the green to be greater than or equal to that, We can roll any number on the green die, ya? If a 2 is rolled on the red die, We can roll any number larger than a 1 on the green die. R1 G123456 R2 G 23456 R3 G 3456 R4 G 456 R5 G 56 R6 G 6 =6+5+4+3+2+1 I think that's 21 of the 36 combinations, isn't it? :o
