Two shooters shoot a target. The known probability to hit the target of the first and second shooter are $0.70$ and $0.80$ respectively. What is the probability that the target is hit after one shot from both shooters?

I tried

$$P_1= 0.7$$



But it seems too simple and probability is too big so i'm not sure i'm on the right way?
