There are 88 balls in a bucket. The balls are numbered from 1 to 88. One ball is randomly selected from the bucket.
What is the probability that ball 55 is chosen?
Since there is only one ball numbered 55 and 88 total balls, the probability of selecting ball 55 is 1/88.
Joey had 40 words to study for a spelling quiz, but he only learned 6 of them. His teacher surprised the class by telling them that the quiz would only have 1 of those 40 words on it. If the teacher chose that 1 word randomly, what is the probability that it was one of the words Joey learned?
The probability that the word chosen is one of the words Joey learned is equal to the number of words Joey learned divided by the total number of words.
So the probability is:
6/40 = 3/20
or
0.15
or
15%.
A class of 17 students is having a drawing. Each student's name is placed on a piece of paper and then placed in a hat. One name is randomly drawn from the hat.
If there are 9 boys in the class, what is the probability that the name drawn is a girl's?
There are 17 students in the class, and 9 of them are boys. That means there are 17 - 9 = 8 girls in the class.
The probability of drawing a girl's name is equal to the number of girls in the class divided by the total number of students in the class.
So the probability is:
8/17
or
0.47
or
47%.
To find the probability of choosing ball number 55, you need to know the total number of balls in the bucket and the number of balls numbered 55.
Total number of balls = 88
Number of balls numbered 55 = 1
The probability of choosing ball 55 can be calculated using the formula:
Probability = Number of desired outcomes / Number of possible outcomes
In this case, there is only 1 desired outcome (choosing ball 55), and there are 88 possible outcomes (total number of balls in the bucket).
So, the probability of choosing ball 55 is:
Probability = 1 / 88
Therefore, the probability of ball 55 being chosen is 1/88.
To find the probability of choosing ball 55, we need to know the total number of balls in the bucket and the number of balls that are ball 55.
In this case, there are 88 balls in total, and since ball 55 is only one of them, there is exactly 1 ball numbered 55.
The probability formula is:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
So, the probability of choosing ball 55 is:
Probability = 1 / 88
Therefore, the probability that ball 55 is chosen is 1/88.
