A factor of 30 is chosen at random. What is the probability, as a decimal, that it is a 2-digit number?
The positive whole-number factors of 30 are:
1, 2, 3, 5, 6, 10, 15 and 30.
So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that
P(factor of 30 chosen is a 2-digit number) = number of two-digit factors ÷ number of factors
=38=3×.125=.375
Answer:
there are 4 decimal places
Step-by-step explanation:
you must solve the math
Adding parentheses in the component 
of the expression may bring an output of 48.
<h3>Procedure - Application of hierarchy rules in a arithmetic expression</h3>
In this question we should make use of hierarchy rules represented by the use of parentheses. The parentheses oblige to make operations inside it before making it in the rest of the formula.
Now we decide to add parenthesis in the component such that the result of the entire expression is 48. We proceed to present the proof:
Adding parentheses in the component of the expression may bring an output of 48. 
<h3>Remarks</h3>
The statement presents mistakes and is poorly formatted. Correct form is shown below:
An expression is shown: 
Using the same expression, add parenthesis so that the value of the expression is 48.
