If the first roll is a 4, the possibilities to add less than 8 are that the second cube roll is 1, 2 or 3.
These are 3 different events out of 6 possilbe ones, which is 3 / 6 = 1 / 2; i.e. half of times.
Then the answer is the first option: 1 / 2

Answer:
The median is 150 minutes.
Step-by-step explanation:
As we know, in our question, we have been told that the distribution of time on social media is known to be NORMAL. So, it’s a NORMAL DISTRIBUTION. And there is a property of normal distribution that it’s mean is equal to median which is also equals to mode.
So we can conclude that:
For Normal Distribution:
Mean = Median = Mode
So, in our question average = 150 minutes = mean
So, according to the property of normal distribution:
Mean = 150 minutes = Median
