Question

The probability of guessing the correct answer to a certain questions is x/3. If the probability of not getting the correct answer is x/5,

Answer 1

Hi friends

Probability of guessing right answer= x/3

Probability of guessing wrong answer =

x/5

We know that,

probability of right + probability of wrong = 1

x/3 + x/5 = 1

5x +3x /15 = 1

8 x = 15

x = 15/8

x = 1.875
