the letters that form the word algebra are placed in a bowl. what is the probability of choosing a letter that is not “a”?
Answer
Explanation:
Step1: Count total letters
The word "ALGEBRA" has 7 letters.
Step2: Count number of 'A's
The word "ALGEBRA" has 2 'A's.
Step3: Calculate number of non - 'A's
Number of non - 'A's is (7 - 2=5).
Step4: Calculate probability
Probability (P=\frac{\text{Number of non - 'A's}}{\text{Total number of letters}}=\frac{5}{7}).
Answer:
(\frac{5}{7})
