Remark
Thank you for the list of shapes. We so many questions where the person lists the question but won't come back to list what will help us answer it. So you are to be commended for taking the time to come back.
There are four of shapes.
The probability of flipping a coin and getting tails is 1/2
The probability of getting one of 1,2,3,4,5,6 is 1/6.
(But the way you wrote it, it is more like certainty. That's because when you write or as you did, it suggests that you can get anything from 1...6.
The probability of getting the square is 1 in 4
So the probability of getting All three conditions is 1/2 * 1/6 * 1/4 = 1/48
If you do mean the dice can be anything, then the probability is 1/2 * 1 * 1/4 = 1/8, which means that the dice is contributing nothing to the situation.
