The probability that Sara wins a raffle is given by the expression n/n+3 Write down an expression, in the form of a combined single fraction, for the probability that Sara does not win.

3/(n + 3)

Step-by-step explanation:

The given probability that Sara wins a raffle draw, P = n/(n + 3)

Given that the sum of all probabilities is 1, we get

The probability that Sara does not win, Q = 1 - P

Therefore;

Q = 1 - n/(n + 3) = (n + 3) - n/((n + 3) = 3/(n + 3)

The probability that Sara does not win, Q = 3/(n + 3)

answer: all of the odd numbers were opened
