30%
Step-by-step explanation:
If a football quarterback enjoys practicing his long passes over 40 yards and misses the first pass 40% of the time, but when he misses on the first pass, he misses the second pass 20% of the time. The probability of missing two passes in a row is 30%.
First pass: 40%
Second pass: 20%
40% and 20% combined/average is 30%.
Therefore, the probability of missing two passes in a row is 30%.
