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

Why is putting rock layers in order by age useful to geologist?
iVinArrow [24]
Rock layers in order is basically natures calendar.

The highest layer is the newest formed layer 
While the deepest layer was the oldest and probably has been there from some time
