A coin is flipped until 3 heads in succession occur. list only those elements of the sample space that require 6 or less tosses.
Mashutka [201]

we are given

A coin is flipped until 3 heads in succession occur

so, firstly, we will find sample space

S={HHH , THHH , HTHHH, TTHHH , TTTHHH , HTTHHH , THTHHH , HHTHHHH, ......}

now, we are given that

list only those elements of the sample space that require 6 or less tosses

so, we can see that sample space

S={HHH , THHH , HTHHH, TTHHH , TTTHHH , HTTHHH , THTHHH , HHTHHHH, ......}

There are infinite such possibilities

so, there are infinite number of elements in space

and we know that

discrete sample space will always have finite elements

but we have infinite number of sample space elements here

so, this is not discrete sample space...........Answer

x=\sqrt{880-8x}\\&#10;D:880-8x\geq0 \wedge x\geq0\\&#10;D:8x\leq880 \wedge x\geq0\\&#10;D:x\leq 110 \wedge x\geq0\\&#10;D:x\in\langle0,110\rangle\\&#10;x^2=880-8x\\&#10;x^2+8x-880=0\\&#10;x^2+8x+16-896=0\\&#10;(x+4)^2=896\\&#10;x+4=8\sqrt{14} \vee x+4=-8\sqrt{14}\\&#10;x=-4+8\sqrt{14} \vee x=-4-8\sqrt{14}\\&#10;\\ x=-4-8\sqrt{14}\not \in D \Rightarrow \boxed{x=-4+8\sqrt{14}}
