short answer: 10
reason: all of the other numbers are multiples of 3
It's even
25 is odd
Square numbers 16, 25, 36, 49, 64, 81, 100
The probability is 21/36 = 7/12
72 is not an odd number because it is divisible by 2. 72/2 = 36.
Only 9 and 15 are odd so the rest can be rejected. 9 is not a triangular number so only 15 is odd and a triangular number.

72 is not an odd number because it is divisible by 2. 72/2 = 36.
Even numbers are divisible by 2, and odd numbers are not. 36/2=18, so 36 is an even number.
71 is the 36th odd number. To find the "nth" odd number, multiply the term number (ex: 36) by two, then subtract one.
6 times 6 = 36, so yes, 36 is a square. 1+2 = 3 3+3 = 6 6+4 = 10 10+5 = 15 15+6 = 21 21+7 = 28 28+8 = 36, so yes, 36 is a triangular number
That number is 36.
Decimal numbers generally are not considered to be odd or even. Only integers are odd or even. So on that basis, 3.6 is not an odd number, but neither is it an even number.
