Transcendent Technologies is deciding between developing a complicated thought-activated software, or a simple voice-activated software. Since the thought-activated software is complicated, it only has a 30% chance of actually going through to a successful launch, but would generate revenues of $50million if launched. The voice-activated software is simple and hence has a 80% chance of being launched but only generates a revenue of $10million. The complicated technology costs 10million, whereas the simple technology costs 2million.

Launching the simplified version would be a mistake for probabilities less than ___?

a.0.6

b.0.7

c.0.8

d.1.0
