Answer:
Option: C is the correct answer.
C. Buying a needle and buying thread are dependent events.
Step-by-step explanation:
let A denotes the events of buying a thread.
and B denote the event of buying a needle.
Then A∩B denote the event of buying a needle and a thread.
Also let P denote the probability of an event.
i.e. we are given:
P(A)=0.15
Also P(B|A)=0.25
As we know that:
As we know that when two events A and B are independent then,
P(A∩B)=∅
otherwise they are dependent events.
Hence, option: C is the correct answer.

<h3>x = 27.5</h3>
Step-by-step explanation:
The picnic area is 20 inches wide in the drawing in her scale of 1 inch : 4 yards.
<h3>What is unitary method ?</h3>
Unitary method is a technique for first solving the value of a single digit unit and from there we can find the value of any given unit.
According to the given question lillian drew a scale drawing of a county park. the scale she used was 1 inch : 4 yards.
The picnic area is 80 yards wide in real life.
∴ The width of the picnic area in here drawing in inches will be
= 80/4 inches.
= 20 inches.
