From a set of eight marbles, five red and three white, we choose one at random. What are the odds in favor of choosing a red marble?
5 red out of eight total
5/8 = .625 probability
HOWEVER you said odds, as in betting odds.
That is not probability but the ratio of success to failure
in this case 5/3
To calculate the odds in favor of choosing a red marble, we need to determine the ratio of favorable outcomes (red marbles) to total outcomes.
Given that there are five red marbles and three white marbles, the total number of marbles is 5 + 3 = 8.
Therefore, the odds in favor of choosing a red marble can be stated as:
Favorable outcomes (red marbles) : Total outcomes = 5 : 8
The odds in favor of choosing a red marble are therefore 5/8.
To calculate the odds in favor of choosing a red marble, we need to determine the number of favorable outcomes and the number of total outcomes.
In this case, we have 5 red marbles and 3 white marbles, making a total of 8 marbles.
The number of favorable outcomes is the number of red marbles, which is 5.
The number of total outcomes is the total number of marbles, which is 8.
Therefore, the odds in favor of choosing a red marble can be calculated as follows:
Odds in favor of red = Number of favorable outcomes / Number of total outcomes
Odds in favor of red = 5 / 8
Simplifying the fraction, we get:
Odds in favor of red = 5/8
So, the odds in favor of choosing a red marble are 5 to 8.
