Imagine we are throwing a five-sided die 50 times. on average, out of these 50 throws, how many times would this five-sided die show an odd number? (1 & 3 & 5)
out of 50 throws

16.6 times because if there is 3 numbers you simply divide it into 50

Try putting the 3/5 which creates a fraction which you can times by 50

3 is how many odd number there are and 5 is how many overall numbers you have, this will create a decimal or fraction that you can times by 50 to get the Answer.
This process generally works for just about any of these questions
