#1/4#

Explanation:

We address each probablility independantly and then multiply the two.

Probability of getting heads is #1/2#, because there's #1# way to get heads out of #2# equally likely outcomes.

The probablility of rolling a #4#, #5#, or #6# on a die is going to be #3/6# because out of #6# equally likely rolls, #3# are greater than or equal to #4#.

We then multiply the two values together.

#1/2times3/6=3/12#

There are three ways for this to happen (heads and #4#, heads and #5#, and heads and #6#) out of #12# possible outcomes. The probability is #3# in #12#, or #1/4#.
