Answer: 1/6
Step-by-step explanation: To find the probability of rolling a 4, let's use our ratio for the probability of an event which is shown below.
Number of favorable outcomes/total number of outcomes
Since only one side of a number cube has a 4 on it, the number of favorable outcomes for rolling a 4 is 1 and since there are six sides to a number cube and it's equally likely that the cube will land on any of these sides, the total number of outcomes is 6.
So the probability of rolling a 4 is 1/6 which is equivalent
to 0.167 or 16.7%.
That means it is't likely that you would roll a 4 for instance but it's just as likely as rolling any other number.
Answer:
20 1/4
Step-by-step explanation:
We can turn the fractions improper to solve
4 1/2= 9/2, 9/2 is the improper fraction so now we multiply
9/2 x 9/2=81/4, 81/4 is improper and isn't one of the choices so we can change it into a mixed fraction.
81/4 is equal to 20 1/4
