Answer:
He will get the first shot 30% of the time, and 30% of the times he makes the first shot he will make the second.
If you multiply 0.3 by 0.3 you will get 0.09 or 9%

Step-by-step explanation:
For two shots Pedro has four outcomes:
1 shot | 2 shot
score | score
score | not score
not score | score
not score | not score
The probability Pedro's shot will score in a lacrosse game is 0.30 and the probability his shot will not score in a lacrosse game is 1-0.30=0.70. So you can count probabilities for all cases:
1. 0.3·0.3=0.09;
2. 0.3·0.7=0.21;
3. 0.7·0.3=0.21;
4. 0.7·0.7=0.49.
In total 0.09+0.21+0.21+0.49=1. The first outcomes is that what you need.
Answer: 0.09.
