#a=3#

Explanation:

This question essentially means what is the value of #a# such that half of the values lie above it?

Normally you would use integrals and a probability function to solve this but this graph is clearly symmetrical with 3 in the middle. You can see that half of the area is between 0 and 3 and the other half is between 3 and 6. Thus #a=3#
