To find the probability of getting a 3 and then a 4 on a six-sided number cube, given that the first number rolled was a 3, we can break it down step by step:
1. Given that the first number rolled was a 3, we already have one favorable outcome (rolling a 3).
2. Since the number cube has six sides, there are a total of six possible outcomes for the second roll.
3. Out of the six sides, only one side has a 4, which is the desired outcome for the second roll.
Therefore, the probability of getting a 3 followed by a 4, given that the first number rolled was a 3, is 1/6. This is because out of the six equally likely outcomes for the second roll, only one of them results in a 4 when the first number rolled was a 3.
So, the correct answer is 1/6.
