The short answer is trial and error. The side lengths "3" and "4" can both be substituted for a² and b² but not c² because their value squared is not high enough since 5² is 25. "c²" as to match the longest side because the smaller numbers will cause the equation to not be true. See Below.
a² + b² = c²
3² + 4² = 5²
9 + 16 = 25
25 = 25
______________________________
a² + b² = c²
4² + 3² = 5²
16 + 9 = 25
25 = 25
______________________________
a² + b² = c²
5² + 4² = 3²
25 + 16 = 9
41 ≠ 9
______________________________
a² + b² = c²
3² + 5² = 4²
9 + 25 = 16
34 ≠ 16

Answer:
c) gives each member of the population a known chance to be selected
Step-by-step explanation:
A sample is said to be a probability sample when each and every unit of the population would have the known chance or the probability i.e. more than zero when selected in the sample
So according to the given options, it is the sample where each member have the known chance to be selected
Therefore the option c is correct
18 liters water, 9 liters orange, 6 liters apple, and 3 liters mango
C. 4,5, 6
