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

Which is one way US workers are affected when job s are outsourced to less developed countries?
Makovka662 [10]
"The main negative effect of outsourcing is it increases U.S. unemployment. The 14 million outsourced jobs are almost double the 7.5 million unemployed Americans. If all those jobs returned, it would be enough to also hire the 5.7 million who are working part-time but would prefer full-time positions."
