Answer:
i. 3/5
ii. 2/5
Explanation:
Solving the problem by any of the students A, B and C is an independent event as solution by one does not restrict the other one from solving
However, the problem will be solved if even one of them solves the question
Now Probability of not solving the question by A, B and C are
PA (not solving a problem) - 1-1/3 = 2/3
PB (not solving a problem) - 1-1/4 = 3/4
PC (not solving a problem) - 1-1/5 = 4/5
ii) Probability of not solving - 2/3*3/4*4/5 = 2 *1/5 = 2/5
i) Probability of solving - 1- Probability of not solving
= 1 - 2/5 = 3/5

Hey There!
The Berlin Wall was built by East German troops and engineers on August 13, 1961. The wall was built to keep west Germans out, but it was built to keep eastern Germans in. Many eastern Germans were fleeing to the west because they felt that Western Germany better represented their ideals, political ideas, and culture. Hopefully this helped!
