There are 36 combinations, of which, 6 are equal to seven and 2 are equal to eleven.Odds of getting seven or eleven are: 2/9Odds of NOT getting a seven or eleven are: 7/9To get exactly 5 sevens, 2/9*2/9*2/9*2/9*2/9(for the five sevens) and 7/9*7/9*7/9*7/9*7/9 (for the 5 NON-sevens).(2^5 * 7^5) / (9^10)You should be able to get the answer from there.
