Answer:
$9$
Step-by-step explanation:
Given: Thea enters a positive integer into her calculator, then squares it, then presses the $\textcolor{blue}{\bf\circledast}$ key, then squares the result, then presses the $\textcolor{blue}{\bf\circledast}$ key again such that the calculator displays final number as $243$.
To find: number that Thea originally entered
Solution:
The final number is $243$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $243$ must be $324$.
As previously the number was squared, so the number before $324$ must be $18$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $18$ must be $81$
As previously the number was squared, so the number before $81$ must be $9$.
The answer to your problem is
Using the probability concept, we have that:
- There is a 0.6286 = 62.86% probability that a randomly selected person is female or prefers mint chocolate chip.
- There is a 0.3714 = 37.14% probability that a randomly selected person prefers cookie and cream or vanilla.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 35 people, out of which 17 are female and 5 are male that prefer mint chocolate chip, hence:
p = (17 + 5)/35 = 22/35 = 0.6286.
There is a 0.6286 = 62.86% probability that a randomly selected person is female or prefers mint chocolate chip.
Out of the same 35 people, 11 people prefer cookie and cream and 2 people prefer vanilla, hence:
p = (11 + 2)/35 = 13/35 = 0.3714
There is a 0.3714 = 37.14% probability that a randomly selected person prefers cookie and cream or vanilla.
