Counting is Not an Easy Task

For any prime number $P$ , let $A_{P}$ be the set of integers $d \in \{1, 2, 3, \cdots 999\}$ such that the power of $P$ in the prime factorization of $d$ is odd. Then the Cardinality of

1: $A_{3}$ is 250

2: $A_{5}$ is 160

3: $A_{7}$ is 124

4: $A_{11}$ is 82

Which of the above Statements is False ?
