It could be any fraction from 5/9 to 7/9.
Hello there!
The correct answer is option C (-∞,10)
Best of luck with your study!
False
A arithmetic sequence is a sequence that has a difference of 2. We see that we have -17 ... and then we have 2 ... and then 21. There is NOT a difference of 2, as we can see. Therefore, yiur answer would be (false).
<span>Lets say the 1st die rolled a 2 -
there would be 2 combinations for which the sum of dice being < 5 :
2,1
2,2
Now say the 2nd die rolled a 2 -
there would be 2 combinations for which the sum of dice being < 5 :
1,2
2,2
Now we want to count all cases where either dice showed a 2 and sum of the dice was < 5. However note above that the roll (2,2) is counted twice.
So there are three unique dice roll combinations which answer the criteria of at least one die showing 2, and sum of dice < 5:
1,2
2,1
2,2
The total number of unique outcomes for two dice is 6*6=36 .
So, the probability you are looking for is 3/36 = 1/12</span>
