Question

Accepted Answer

Step 1: Identify prime numbers between 50 and 76.
Prime numbers in this range are: 53, 59, 61, 67, 71, 73.

Step 2: Calculate their sum.
53 + 59 + 61 + 67 + 71 + 73 = 384

Step 3: Count the number of prime numbers.
There are 6 prime numbers.

Step 4: Calculate the average.
Average = Sum / Number of primes = 384 / 6 = 64

Correction: Rechecking sum:
53 + 59 = 112
112 + 61 = 173
173 + 67 = 240
240 + 71 = 311
311 + 73 = 384
Average = 384 / 6 = 64

The correct average is 64, so option 4 is correct.
