An experiment consists of selecting a number at random between 0 and 9 inclusive, and a letter from the English alphabet. What is the size of the sample space of this experiment?

A) 35

B) 36

C) 52

D) 234

E) 260

For this item, we first identify the number of ways in which choosing a number and a letter can be done. For numbers 0 to 9, there are 10 ways and for the letter in the English alphabet, there are 26. Multiplying both numbers, we get 260. Thus, the answer is letter E.
