Using Dax to check if grouped rows match

[Apocalipia]

I have data in the format below (minus the far right column)

EmailAddress	CourseTitle	Complete	AllComplete
1@1.com	Course1	true	false
1@1.com	Course2	true	false
1@1.com	Course3	false	false
2@1.com	Course1	true	true
2@1.com	Course2	true	true
2@1.com	Course3	true	true

Using DAX, I'd like to know if it is possible to add the far right column above. So, if all Complete values are true (grouped by EmailAddress), then the value in AllComplete should be true.
Is this possible, and if so, could an explanation be given as to how?

Thanks in advance
