Question
A word game has 100 tiles, 98 of which are letters and 2 of which are blank. The numbers of tiles of each letter are shown. You randomly draw 1 tile, set it aside, and then randomly draw another tile.Event A: The first tile is a consonant.Event B: The second tile is a vowel.Find the probability that both events A and B will occur. Round your answer to the nearest tenth.about
Solution
To find the probability that both events A and B will occur, we need to follow these steps:
-
Determine the total number of consonants and vowels:
- Let's assume the number of consonants is and the number of vowels is .
- The total number of tiles is 100, with 2 being blank, so there are 98 letter tiles.
-
Calculate the probability of drawing a consonant first (Event A):
- The probability of drawing a consonant first is .
-
Calculate the probability of drawing a vowel second (Event B) given that the first tile was a consonant:
- After drawing a consonant, there are 99 tiles left.
- The number of vowels remains .
- The probability of drawing a vowel second is .
-
Calculate the combined probability of both events A and B:
- The combined probability is the product of the individual probabilities:
-
Substitute the values of and into the formula:
- Let's assume and (these values are hypothetical and should be replaced with the actual counts from the game).
-
Calculate the probability:
-
Convert the probability to a percentage and round to the nearest tenth:
Therefore, the probability that both events A and B will occur is approximately 23.8%.
