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.

Answer:
see explanation
Step-by-step explanation:
The width w is 4 feet longer than two times the length , then
w = 2l + 4
The area (A) of the rectangle is length × width , then
A = l(2l + 4) ← distribute parenthesis
A = 2l² + 4l
Given A = 16
2l² + 4l = 16
Subtract 16 from both sides
2l² + 4l - 16 = 0 ( divide through by 2 )
l² + 2l - 8 = 0 ← in standard form
(l + 4)(l - 2) = 0 ← in factored form
Equate each factor to zero and solve for l
l + 4 = 0 ⇒ l = - 4
l - 2 = 0 ⇒ l = 2
However l > 0 then l = 2
and w = 2l + 4 = 2(2) + 4 = 4 + 4 = 8
The length of the rectangle is 2 feet and
the width is 8 feet
