TARGET 95+ SERIES|ONE SHOT

8 clay targets are arranged as shown. If N be the number of different way they can be shot (one at time) if no target can be shot until the target(s) below it have been shot. Find the ten's digit of N.

The adjoining diagram shows 8 clay targets, arranged in 3 columns to be shot by 8 bullets. The number of ways in which they can be shot such that no target is shot before all the targets below it,if any,are first shot is (A) 560 (B) 72 (C) 40320 (D) none of these

The following question, a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series. 95, 115, 145, 155, ?

Five shots are fired at a target.If each shot has a probability 0.6 of hitting the target,what is probability that the target will at least once?

A can hit a target 3 xx in 6 shots; B,2 xx in 4 shots and C,4 xx in 4 shots.All of them fire at a target independently.The probability that the target will be hit is

A can hit a target 4 times in 5 shots , B can hit a target 3 times in 4 shots , C can hit a target 2 times in 3 shots, All the three fire a shot each. What is the probability that two shots are at least hit ?

The probability that a marksman will hit a target is given as (1)/(5) . Then, the probabiltiy that atleast one hit in 10 shots is
