Question

if two dice are rolled what is the probability that shows a total of 9 or 11

Answer 1

Let the probability be x
PROBABILITY=No.of favourable outcomes/No. of possible outcomes
3+6=9
5+4=9
4+5=9
6+3=9

Answer 2

there are 36 outcomes
$sum \: of \: 9 = (3 \: 6) \: (5 \: 4) \\ \: (4 \: 5) \: (6 \: 3) \\ sum \: of \: 11 = (5 \: 6) \: (6 \: 5)$
probability=6/36 = 1/6
