If the odds of winning a raffle are 13:225, what is the probability of winning?
probability = 13/225 = .058 = 5.8%
probability = 13/(13+225)
= 13/238
= 0.0546...
To find the probability of winning a raffle, we need to calculate the ratio of the number of favorable outcomes (winning) to the total number of possible outcomes. In this case, the odds of winning are given as 13:225.
The odds can be expressed as a fraction by dividing the two numbers in the ratio. In this case, it would be 13/225.
To convert this fraction into a probability, we need to add the numerator and denominator and divide the numerator by this sum. So, the probability of winning is calculated as:
P(winning) = 13 / (13 + 225)
P(winning) = 13 / 238
P(winning) ≈ 0.0546 or 5.46%
Therefore, the probability of winning the raffle is approximately 0.0546 or 5.46%.
