# As the number of tosses of a coin increases, the ratio of the number of heads to the total number of tosses will be 1/2. Is it correct? If not, write the correct one.

**Solution:**

As the number of tosses of a coin increases, the ratio of the number of heads to the total number of tosses will be near to 1/2 but not exactly 1/2

Therefore, the statement is false.

**✦ Try This: **The class marks of a continuous distribution are : 1.05, 1.15, 1.25, 1.35, 1.45, 1.55 and 1.65

Is it correct to say that the last interval will be 1.56 - 1.74? Justify your answer.

We know that

__Class mark__ is the mid point of a class interval

The difference between two consecutive class marks is equal to the class size

1.15 - 1.05 = 0.1

1.25 - 1.15 = 0.1

1.35 - 1.25 = 0.1

Here the class size is 0.1

Class interval 1.56 - 1.74, (1.74 - 1.56) = 0.18 is not equal to the class size.

So it cannot be the last interval of the class marks

Therefore, class interval 1.56 - 1.74 cannot be the correct class interval for the class marks given.
