Question

You fllp a fair coln 7 times in a row. Let X be the number of heads that come up. Which of the following cannot be a
possible value of X?
2
0
7
16

Answer 1

Answer:

16

Step-by-step explanation:

Given

A coin

$n = 7$ --- Number of flips

$x \to heads$

Required

Which can't be the value of x

From the question, we understand that the coin was flipped 7 times.

This means that, the highest occurrence of head is:

$x = 7$

And the list is:

$x = 0$

So, the range of x is:

$x = \{0,1,2,....,7\}$

In the above range, only (16) is out of range.

Hence:

$x \ne 16$ --- Number of heads can't be 16
