Question

Hey mates!!!

The probability of guessing the correct answer to a certain question is x/3.If the probability of not guessing the correct answer is x/5,then find the value of x.... (Plzzz urgent )​

Answer 1

Not guessing the correct answer probability = 1 - x/3

As 1 - x/3 = x/5

1 = x/5 + x/3

1 = 3x + 5x )/ 15

8x= 15

x= 15/8

Answer 2

x/3 + x/5 = 1

5x + 3x / 15 = 1

5x + 3x = 15

8x = 15

x = 15/8
