The probability that the total number of heads in all the coin tosses equals 12 is 0.0273.
Given a fair dice and tossing a fair coin sixteen times.
We have to find the probability that the total number of heads in all the coin tosses equals 12.
The probability lies between 0 and 1.
Probabiltiy of coming head when the coin is tossed 1 time is 0.5 and probability of coming tails is also 0.5.
Let X shows the sum of heads while tossing.
P(X=12)=?
We can find the probability using binomial theorem.
=![16C_{12} (0.5)^{12} (0.5)^{2}](https://tex.z-dn.net/?f=16C_%7B12%7D%20%280.5%29%5E%7B12%7D%20%280.5%29%5E%7B2%7D)
We have to toss sixteen times and out of 16 times we need head 12 times.
=16!/12!4!*0.00024*0.0625
=1820*0.000015
=0.0273
Hence the probability that the total number of heads in all the coin tosses equals 12 is 0.0273.

Answer: Length = 12cm , width = 21cm
Step-by-step explanation:
Let the length be x , then the width is x + 9, That is
Length = x
Width = x + 9
The formula for calculating the perimeter of a rectangle is given by:
Perimeter = 2 ( Length + Width )
substituting the values , we have :
66 = 2 ( x + x + 9 )
66 = 2 ( 2x + 9 )
divide through by 2
66/2 = 2x + 9
33 = 2x + 9
subtract 9 from both sides
33 - 9 = 2x
24 = 2x
divide through by 2
therefore :
x = 12
This means that
Length = 12cm
Width = 12 + 9 = 21 cm
