Question

A can hit the target 3 times in 6 shots, B 2 times in 6 shots and C 4 times in 6 shots. They fire a volley. What is the probability that at least 2 shots hit?​

Answer 1

Answer:

Total no of shots-18

No of shots hit by A-3

No of shots hit by B-2

No of shots hit by C-4

So, total no of shots hit-4+2+3=9

Probability(Atleast 2 shots are hit) =No of shots hit more than 2 /Total no of shots

Sample Events= 2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18

So,

P=17/18

Answer 2

Answer:

Prabability÷No. of favourable outcomes

No. of total outcomes
