Answer:
and
.
Step-by-step explanation:
Let be the smaller one of the two number.
must be a positive integer. The other number would be
.
The question states that the product of the two numbers is . In other words:
.
Rearrange this equation and solve for :
.
The first root of this quadratic equation would be:
.
Similarly, the second root of this quadratic equation would be:
.
Since the question requires that both numbers should be positive, . Therefore, only
is valid.
Hence, the two numbers would be and
, which is
.
To get a sum of 3, you must roll a 1 and a 2. To get a sum of 8, you must roll a 5 and 3, or two 4's.
There are two ways of rolling a 1 and a 2, two ways of rolling a 5 and a 3, and one way to roll two 4's.
There are
possible outcomes when rolling two such solids.
So the probability of getting a sum of 3 or 8 is
