Hi
My 16 year old son had a question in one of his exams about probability that I could not answer - could anyone help?
I know that P(X ∪ Y) = P(X) + P(Y) - P(X ∩ Y)
However the problem was this:
Probability of number of goals in a football/soccer game:
probability of more than one goal: 90% (9/10)
probability of less than 4 goals: 85% (8/10)
No further information was given
What is the probability of more than one goal but less than 4 goals?
Am i using the right formula? are these non-mutually exclusive?
Thanks!
