a set of cards is numbered 1-20 what is the probability of choosing the card numbered 1
1/20 = .05 = 5%
Number of required outcome:19 Number of possible outcome:20 equal to 19over20
To find the probability of choosing the card numbered 1 out of a set of cards numbered 1-20, we need to know the total number of cards in the set. Assuming there are 20 cards in total:
The probability can be calculated by dividing the number of favorable outcomes (choosing the card numbered 1) by the total number of possible outcomes (choosing any card from the set).
In this case, the number of favorable outcomes is 1, as there is only one card numbered 1. The total number of possible outcomes is 20 because there are 20 cards in the set.
Therefore, the probability of choosing the card numbered 1 is:
1 (number of favorable outcomes) / 20 (total number of possible outcomes) = 1/20
So, the probability of choosing the card numbered 1 from a set of cards numbered 1-20 is 1/20.
To find the probability of choosing the card numbered 1 out of a set of cards numbered from 1 to 20, we need to know the total number of cards in the set.
Let's say there are 20 cards in the set from 1 to 20. Since there is only one card numbered 1, the probability of choosing that particular card is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
In this case, the number of favorable outcomes is 1 (since there is only one card numbered 1), and the number of possible outcomes is 20 (since there are 20 cards in total).
So, the probability of choosing the card numbered 1 is:
Probability = 1 / 20 = 0.05 or 5%
