the letters that form the word algebra are placed in a bowl. what is the probability of choosing a letter other than “a”?
Answer
Explanation:
Step1: Count total letters
The word "ALGEBRA" has 7 letters.
Step2: Count number of 'A's
There are 2 'A's in "ALGEBRA".
Step3: Calculate number of non - 'A' letters
Number of non - 'A' letters = 7 - 2 = 5.
Step4: Calculate probability
Probability of choosing a non - 'A' letter = $\frac{\text{Number of non - 'A' letters}}{\text{Total number of letters}}=\frac{5}{7}$.
Answer:
C. 5/7
