Predicting product Failures for next 10 years, given MTBF and volume

[Ewgf87]

Hi,

I'm working on a project at the moment and have been given the task of calculating the prdicted volume of failures of 80,000,000 units that have already been sold, given that the theoretical MTBF, (Mean time between failures) is 42,462.85 hours, or 4.84 years. I need to predict the volume of failures for the next 10 years. Is this possible given the info that i have?

If anyone can help me it would be great!
Thanks.
