total there are 8 possibilities when a fair coin is tossed thrice out of which probability for exactly three tails is 1/8
probabolity for atleast 2 tails(it means kam se kam 2 tails) is 4/8 that is 1/2
probability for atmost two tails(it means zyada se zyada 2 tails) is 7/8
probabolity for atleast 2 tails(it means kam se kam 2 tails) is 4/8 that is 1/2

Since coin is tossed 3 times and the total no. of possible outcome per time are 2 so total possible outcomes are 2^3 = 8. Now, the possibilities are
TTT HHH HTT TTH HTH THT HHT TTH. So answers are 1/8, 1/2, 3/8
