Answer:
B. 3
Step-by-step explanation:
A common difference in an arithmetic sequence is the value the terms in the sequence vary from one to another.You can find one term to another by adding or subtracting the common difference.
In this case, the terms are 2,5,8,11,.....
From the first term to the second term, the difference is, 5-2=3
From the second term to the third term, the difference is, 8-5=3
From the third term to the fourth term the difference is=11-8=3
Hence the common difference in this arithmetic sequence is 3

Step-by-step explanation:
A gunner fires 10 bullets at a target, with the probability of hitting the target at each shot is p = 0.8. Know that, if all 10 bullets hit the target, the target is definitely destroyed. If 2-9 bullets hit the target, the target is destroyed with a probability of 80%. If only 1 bullet hits the target | then the target is destroyed with a probability of 20%. What is the probability that the target is destroyed?
