Probability of drawing a single digit number:
There are a total of 100 cards, out of which 9 cards (1 to 9) are single-digit numbers. Therefore, the probability of drawing a single-digit number can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 9 / 100 = 0.09 or 9%
Probability of drawing a two-digit number:
There are a total of 100 cards, out of which 90 cards (10 to 99) are two-digit numbers. Therefore, the probability of drawing a two-digit number can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 90 / 100 = 0.9 or 90%
Probability of drawing a three-digit number:
There are no three-digit numbers in the given set of cards. Therefore, the probability of drawing a three-digit number is 0.
Probability of drawing a multiple of 9:
A number is a multiple of 9 if it is divisible by 9. There are a total of 11 multiples of 9 in the given set of cards (9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99). Therefore, the probability of drawing a multiple of 9 can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 11 / 100 = 0.11 or 11%
Probability of drawing a multiple of 5:
A number is a multiple of 5 if it is divisible by 5. There are a total of 20 multiples of 5 in the given set of cards (5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100). Therefore, the probability of drawing a multiple of 5 can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 20 / 100 = 0.2 or 20%
In summary:
- The probability of drawing a single-digit number is 0.09 or 9%.
- The probability of drawing a two-digit number is 0.9 or 90%.
- The probability of drawing a three-digit number is 0.
- The probability of drawing a multiple of 9 is 0.11 or 11%.
- The probability of drawing a multiple of 5 is 0.2 or 20%.
There are a total of 100 cards, out of which 9 cards (1 to 9) are single-digit numbers. Therefore, the probability of drawing a single-digit number can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 9 / 100 = 0.09 or 9%
Probability of drawing a two-digit number:
There are a total of 100 cards, out of which 90 cards (10 to 99) are two-digit numbers. Therefore, the probability of drawing a two-digit number can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 90 / 100 = 0.9 or 90%
Probability of drawing a three-digit number:
There are no three-digit numbers in the given set of cards. Therefore, the probability of drawing a three-digit number is 0.
Probability of drawing a multiple of 9:
A number is a multiple of 9 if it is divisible by 9. There are a total of 11 multiples of 9 in the given set of cards (9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99). Therefore, the probability of drawing a multiple of 9 can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 11 / 100 = 0.11 or 11%
Probability of drawing a multiple of 5:
A number is a multiple of 5 if it is divisible by 5. There are a total of 20 multiples of 5 in the given set of cards (5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100). Therefore, the probability of drawing a multiple of 5 can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 20 / 100 = 0.2 or 20%
In summary:
- The probability of drawing a single-digit number is 0.09 or 9%.
- The probability of drawing a two-digit number is 0.9 or 90%.
- The probability of drawing a three-digit number is 0.
- The probability of drawing a multiple of 9 is 0.11 or 11%.
- The probability of drawing a multiple of 5 is 0.2 or 20%.
