An archer has two attempts to hit a target. The probability that his first arrow hits is 0.4 and the probability that the second arrow hits is 0.5 Given that the probability that he hits the target with both arrows is 0.25, find the probability that he misses the target with borrow arrows.

I don't understand why the probability that he hits the target with both arrows is 0.25...

0.5*0.4 = 0.2 - shouldn't that be the probability of hitting the target twice?

thank you!
