Probability helps us to know the chances of an event occurring. The probability of selecting an even number or multiple of 13 is 13/25.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.

Number of even numbers between 1 to 25 = 22
Number of multiple of 13 between 1 to 25 = 1
The probability of selecting an even number or multiple of 13 is,
Probability = (12+1)/25 = 13/25
Hence, The probability of selecting an even number or multiple of 13 is 13/25.

Answer:
Probability both are hopelessly romantic = 0.0169
Probability at least one is hopelessly romantic = 0.2431
Step-by-step explanation:
We are given that about 1313% of the population of a large country is hopelessly romantic.
Also, given two people are randomly selected.
Firstly, Let <em>Probability that the population of a large country is hopelessly romantic = P(R) = 0.13 </em>
(a) Probability both are hopelessly romantic is given by = Probability that first person is hopelessly romantic
Probability that second person is hopelessly romantic
=
= 0.13
0.13 = <u>0.0169</u>
(b) Now, Probability that the population of a large country is not hopelessly romantic = P(R') = 1 - P(R) = 1 - 0.13 = 0.87.
So, Probability at least one is hopelessly romantic is given by = 1 - Probability that none of them is hopelessly romantic
=
= 1 - (0.87
0.87)
= 1 - 0.7569 = <u>0.2431</u>
Answer and explanation:
Since a quarter(1/4) of paint covers 80 square feet, a whole paint would cover 80×4= 320 square feet of the wall
Remaining part of the wall left unpainted after using one whole paint
480-320= 160 square feet
Therefore paint required for remaining unpainted part
= 160/80= 2 quarters of paint(1/4+1/4)= 1/2 paint
Total paint required for the wall = one whole paint + half paint = 1+1/2= 1 1/2
Total paint required is one and half
Or
We divide area of wall by area of wall covered by each quarter
480/80=6 quarters of paint
6 quarters of paint = 1/4+1/4+1/4+1/4+1/4+1/4
We still get same answer
= 1 1/2
Answer:
-2
Step-by-step explanation:
-4x^3 = 32
x^3 = -8
take the cube root of both sides.
x = -2
