Letter tiles a in a bag. Without looking I am going to draw one tile.
Here are the letter tiles O,I,S,P,L,A
What are my chances of drawing a vowel?
A. 0.3
B. 0.05
C. 0.5
D. 3
You take all the numbers you can draw and add them up. In this case that is 6. Then you take the numbers you want to draw (In this case vowels) which is 3. You put 6 on the bottom of the fraction and 3 on top. That leaves you with 3/6. Once simplified or put into decimal form you get 0.5.
0.1
10
To calculate the chances of drawing a vowel from the given letter tiles, you first need to identify which letters in the tile set are vowels:
- The vowels in the given set are 'O', 'I', 'A'.
Next, count the number of vowel tiles in the set:
- There are three vowel tiles in total.
Now, divide the number of vowel tiles by the total number of tiles in the set:
- The total number of tiles in the set is six.
- So, the chances of drawing a vowel are 3/6 = 0.5.
Therefore, the correct answer is option C. 0.5, which represents a 50% chance of drawing a vowel.
A board game uses a bag of 105 lettered tiles. You randomly choose a tile and then return it to the bag. The table shows the number of vowels and the number of consonants after 50 draws.
A tally chart. The first column is vowel. It has 3 groups of 5 tally marks and 3 more tally marks in it. The second column is consonant. It has 6 groups of 5 tally marks and 2 more tally marks in it.
Predict the number of vowels in the bag.
There are
vowels in the bag.
