Answer
$\frac{1}{36}$
Work Step by Step
We know that $probability=\frac{\text{number of favorable outcomes}}{\text{number of all outcomes}}$
The events are independent, so we can find the probability of all of them happening by finding the probability of them happening individually and multiplying those.
The probability of the yellow: $\frac{2}{6}=\frac{1}{3}$, the probability of the $4$: $\frac{1}{6}$, the probability of the odd number: $\frac{3}{6}=\frac{1}{2}$, thus the probability of all of them happening is: $\frac{1}{3}\frac{1}{6}\frac{1}{2}=\frac{1}{36}$
