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
(1)southeast that's what I think
The last statement is the correct answer. However, the second question is theoretically historically correct, for Иосиф Сталин (Joseph Stalin) practically controlled the entire government of the USSR with his oppressive ultra-authoritarian non-democratic Stalinist-"Communist" regime.
A i think is the correct answer
