1
(A)
(C)
2
(D) 3​

Answer 1

Answer:

Probability Of Guessing The Correct Answer = x/3

Probability of Not Guessing The Wrong Answer = 1 - x/3 --- to test this 

x / 5 = 1 -x/3                                                           take example 

x/5 = (3 - x) / 3                                                        of 1 coin tossed

3x = 5(3 - x)                                                            in air and let assume

3x = 15 - 5x                                                             P of getting tail is 

3x + 5x = 15                                                            25% so P of getting

8x = 15                                                                    Head is 1 - 25% 

x = 15/8                                                                   which is 75%

Value of x is 15/8
