Final answer:

To find the probability that the sum is odd and the number on one of the dice is a 1, divide the number of favorable outcomes by the total number of possible outcomes.

Step-by-step explanation:

To find the probability that the sum is odd and the number on one of the dice is a 1, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.

  1. There are 3 odd numbers on a dice: 1, 3, and 5.
  2. There is 1 favorable outcome for getting a 1 on one of the dice.
  3. Since there are 6 possible outcomes on each dice, the total number of outcomes is 6 * 6 = 36.

Therefore, the probability is 1/36 or approximately 0.0278.
