There are 9 balls in the urn with numbers: 2 4 5 7 8 10 11 14 15. What is the probability that a randomly drawn ball will be with an odd number?

To find out the probability of the event “a randomly drawn ball must have an odd number”, we use the formula: Р (odd number) = n / m, where n – positive outcomes (n = 4 balls: numbers 5, 7, 11, 15); m – all outcomes (m = 9 balls (all balls in the urn)).

Let’s perform the calculation: P (odd number) = n / m = 4/9 = 4/9 ≈ 0.444 (4) or 44.4 (4)%.

Answer: The probability of the event “a randomly drawn ball must have an odd number” is 44.4 (4)%.
