Dice and coin

A number cube is rolled and a coin is tossed. The number cube and the coin are fair. What is the probability that the number rolled is greater than 2 and the coin toss is head?

Correct result:

p =  0.3333

Solution:

$p={\displaystyle \frac{4}{6}}\cdot {\displaystyle \frac{1}{2}}={\displaystyle \frac{1}{3}}=0.3333$
