Answer: 
Step-by-step explanation:
Given
Sample space is 
There are 8 element in sample space which indicates the outcome of tossing a coin three times
Probability of obtaining at least one head



<span>So the equation: (x+8) divided by 2 =24</span>
In the event that you are asking to devide parts, we will use the equation
·X+X²=Y
We Plug in our parts
·4x+1x=5x(Y)
We then substitute
·4x+1x=250(5x)
Then we devide Y(250) by the number of parts total.
·5 parts total.
·250/5=50
·1 part=50.
Next we substitute.
·200(4)+50(1)=250(5)
-In conclusion your answer is 50£:200<span>£, i hope this is the answer you are looking for, feel free to post your questions here in brainly in the future.</span>
