Concept explainers
To find: The score of two heads more than half the time or less than half the time in the given condition.
Answer to Problem 1.3E
The explanation is given below.
Explanation of Solution
Given:
The given condition is as given:
The experiment repeats many times of tossing four coins.
The possible outcome of four coins tossed for one time are given as:
Here the expected numbers of heads are
However the large number of times if we repeat the experiment, we will get the same possible outcomes and most probability the expected numbers of heads will also be
So It can be concluded that less than twelve times of repeating the experiment we will score two heads more than half the time and more than twelve times of repeating the experiment we will score two heads less than half the time.
