**The table above represents the outcome of throwing a dice 100 times. What is the probability of obtaining at least 4?**

**A. ½****B. 2/5****C. ¾****D. 1/5**

**QUICK ANSWER…**

**B**

**SOLUTION****… **** **

**A dice is a small cube with points 1 to 6 on each of the six sides. An example of a dice is one of the pieces of cubes used to play the popular Ludo game.**

**Now, to find the probability of obtaining at least 4 in all throws, we will have to find the number of throws that yielded 4 and above (that is 4, 5, and 6)**

**4 = 16**

**5 = 10**

**6 = 14**

**At least 4 = 16 + 10 + 14 = 40**

**Probability = number of required outcomes/numbers of possible outcomes**

**Probability of obtaining at least 4 = 40/100 = 4/10 = 2/5**

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

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

**QUICK TIPS…**

**You may please note the****se/this****:**

**“At least 4” means**__4 and above__
