Question

If odds in favour of X solving a problem are 4:3 and odds against Y solving the same problem are 2:3. Find probability of: X solving the problem

Answer 1

Let X ≡ the event that X solves the problem

Y ≡ the event that Y solves the problem

Odds in favour of X solving the problem are 4 : 3

∴ P(X) = `4/(4 + 3)`

= `4/7`
