The primes are 23, 29, and 31.
There are three: 23, 29 and 31
The median is the middle number when the numbers are listed in order; if there is an even number of numbers, the median is the mean of the middle two. 35,380 - two numbers - two is even, therefore median is the mean of the middle two, ie the mean of 35 and 380: median = (35 + 380) ÷ 2 = 207.5
None. If you add two even numbers, you'll end up with another even number.
20
The three prime numbers between 20 and 35 are 23, 29, and 31.
if you include both 20 and 35, 16 if you don't include 20 and 35, 14 if you only include one of the numbers but not the other, 15
