There is insufficient information in the question to answer it. You did not specify how many dice were involved. Please restate the question.
In the meantime, I will give a generalized answer.
If the probability of rolling a straight is n, then the probability of rolling straight three times in a row is n3. For instance, with three dice, the probability of rolling a straight is 1 in 36, neglecting (i.e. allowing for) wrap-around straights, and ignoring (sorry, but the math is too complex and does not serve the answer anyway) the fact that straights can go in either direction. That 1 in 36 is n=0.02778. The probability of doing that 3 times in a row, then, is 0.00002143.
3 out of 18
The probability of rolling a 3 with a standard die is 1 in 6. The probability of doing that two times in a row is 1 in 6 squared, or 1 in 36.
The probability of rolling an odd number is 3/6 (or rather, 1/2), so the probability of rolling an odd number three times in a row is 1/2^3 is 1/8 or 12.5%.
The probability of rolling a 3 is 1/6.
Even numbers: 2, 4, 6, the probability to get an ven number is 3/6 = 1/2 The probability to get 4 even number in a row is then (1/2)4 = 1/24 = 1 / 16 It is the same probability to get 4 odd numbers (1,3,5) in a row

1:24 one in 24 rolls
The probability of rolling a 3 on a die are 1/6. Since each roll is an independent event, the probability of rolling a 3 4 times in a row is (1/6)4 or 1/1296.The odds of something happening are the chances of it happening vs. the chances of it not happening. The chance of not rolling a 3 4 times in a row is 1-(1/1296) or 1295/1296.Therefore the odds are 1:1295
the chances of rolling doubles once is 1 in 6; 3 times in a row it is 1 in 216. It does not make any difference after how many times you rolled the dice before.
The probability of rolling a 3 is 1/6.
The probability of rolling the 3 is (1/6).The probability of rolling the 1 is (1/6).The probability of rolling the 3 and then the 1 is (1/6) x (1/6) = (1/36) = about 2.78% (rounded)
The probability of rolling 6 dice and getting 1 2 3 4 5 and 6 all in a row is one in 720, because you are talking about the permutations of six things taken six at a time, which is 6 factorial.
Even numbers: 2, 4, 6, the probability to get an ven number is 3/6 = 1/2 The probability to get 4 even number in a row is then (1/2)4 = 1/24 = 1 / 16 It is the same probability to get 4 odd numbers (1,3,5) in a row
2/6 or 1/3 or 0.3333.
