**A.**** 1****/****8**

**B.**** 2****/****15**

**C.**** 3****/****16**

**D.**** 7****/****8**

**QUICK ANSWER…**

**A**

**DETAILS…**

**The probability that a number selected at random from 41 to 56 is a multiple of 9**** is = 1/8**

**Numbers from 41 to 56 = 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, and 56.**

**Total number occurrence = 16**

**Numbers that are multiples of 9 (between 41 and 56) = 45, and 54.**

**Total number of occurrence of the numbers that are multiples of 9 is = 2**

**Th****us, the ****probability that a number selected at random from 41 to 56 is a multiple of 9**** is = 2/16 = 1/8.**

**Now for the right answer to the above question:**

**Option A is correct.****Option B is not correct.****C is incorrect.****D is not the correct answer.**

**KEY-POINTS…**
