There are twelve instances where the integers from 1 to 200 contain the digit 1 at least twice:-11,101,110,111,121,131,141,151,161,171,181,191.
"MMVII" is the year 2007, represented as a Roman numeral. (M= 1000, twice, V=5, I=1, twice. 1000+1000+5+1+1 = 2007.)
The chance of rolling a 1 on a six-sided die is 1 in 6. To find the probability of rolling a 1 twice in a row, you multiply the probabilities of each event: (1/6) * (1/6) = 1/36. Therefore, the probability of rolling a 1 twice in a row is 1 in 36, or approximately 2.78%.
