The probability that one is selected is the likelihood
The probability that one is selected at least once is 0.704
<h3>How to calculate the probability?</h3>
The sample space is given as:
S = {1,2,3}
The probability that 1 is not selected at all is:
P'(None) = 2/3
The probability that one is selected at least once is calculated using the following complement rule
P(At least once) = 1 - P(None)^3
This gives
P(At least once) = 1 -(2/3)^3
Evaluate
P(At least once) = 0.704
Hence, the probability that one is selected at least once is 0.704

Answer:5
Step-by-step explanation:
Answer: 9 meters
Step-by-step explanation:
A line between two opposite corners splits the floor into two right angled triangles, therefore we can use Pythagoras’ Theorem which is:
a^2 + b^2 = c^2
where c is the hypotenuse, and a and b are the other two sides.
Hypotenuse in this question is 15 metres while one side is 12 metres. The length will now be:
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
b^2 = 15^2 - 12^2
b^2 = 225 - 144
b^2 = 81
b = ✓81
b = 9m
The length of the storage unit is 9m
