What is the probability of rolling?An odd number on the first roll of a six sided cube and rolling an even number on the second roll

1 answer

There are a total of 6 possible outcomes on a six-sided cube (numbers 1 through 6). Out of these 6 outcomes, 3 are odd numbers (1, 3, 5) and 3 are even numbers (2, 4, 6).

The probability of rolling an odd number on the first roll is 3/6 = 1/2.

Given that an odd number was rolled on the first roll, there are now only 2 odd numbers left for the second roll and 3 even numbers. Therefore, the probability of rolling an even number on the second roll is 3/5.

To find the probability of both events happening (rolling an odd number on the first roll and an even number on the second roll), we multiply the probabilities:

P(first roll odd) * P(second roll even) = (1/2) * (3/5) = 3/10

Therefore, the probability of rolling an odd number on the first roll of a six-sided cube and rolling an even number on the second roll is 3/10 or 0.3.
