Question 1136593
<br>
Reasoning logically without any formal mathematics, a 1 is one of three possible odd number outcomes with equal probability, and 2 is one of three possible even number outcomes with equal probability.  Therefore the probability of tossing a 1 or 2 with this weighted die is 1/3.<br>
Mathematically, we have 6 outcomes, with three of the outcomes having twice the probability of the other three.  So
(x+x+x)+(2x+2x+2x) = 1  -->  x = 1/9<br>
P(1) = x = 1/9
P(2) = 2x = 2/9
P(3) = x = 1/9
P(4) = 2x = 2/9
P(5) = x = 1/9
P(6) = 2x = 2/9<br>
P(1 OR 2) = 1/9 + 2/9 = 3/9 = 1/3
