A coin is tossed 15 times and the outcomes are recorded as follows : H T T H T H H H T T H T H T T. The chance of occurence of a head is 50 per cent. State whether the statement is true or false.

Solution:

Given, A coin is tossed 15 times and the outcomes are recorded as follows :

H T T H T H H H T T H T H T T.

The chance of occurence of a head is 50 per cent.

We have to determine if the given statement is true or false.

Total number of occurrence = 15

Number of occurrence of head = 7

Percentage of occurrence = number of favourable occurrence/total number of occurrence × 100

= 7/15 × 100

= 700/15

= 46.6%

Therefore, the required percent is 46.6%

✦ Try This: A coin is tossed 12 times and the outcomes are recorded as follows : H T T H T H H H T T H T . The chance of occurence of a tail is 50 per cent. State whether the statement is true or false.
