Using the concept of probability, the probability of not landing on <em>yellow or red at all</em> is 1/4.
<u>Creating</u><u> </u><u>a</u><u> </u><u>square</u><u> </u><u>model</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>two</u><u> </u><u>spins</u><u> </u><u>:</u>
- Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)
___ R ___ B ___ G ___ Y
R_ RR __ RB __ RG __ RY
B_ BR __ BB __ BG __ BY
G_ GR __GB __ GG __GY
Y_ YR __ YB __ YG __ YY
- <em>Sample</em><em> </em><em>space</em><em> </em><em>=</em><em> </em><em>4²</em><em> </em><em>=</em><em> </em><em>16</em>
<u>Combinations</u><u> </u><u>without</u><u> </u><u>red</u><u> </u><u>and</u><u> </u><u>yellow</u><u> </u><u>:</u>
- {BB, BG, GB, GG}
- <em>Number</em><em> </em><em>of</em><em> </em><em>selections</em><em> </em><em>without</em><em> </em><em>red</em><em> </em><em>or</em><em> </em><em>yellow</em><em> </em><em>=</em><em> </em><em>4</em><em> </em>
<u>Recall</u> :
- <em>Probability</em><em> </em><em>=</em><em> </em><em>required</em><em> </em><em>outcome</em><em> </em><em>/</em><em> </em><em>Total possible</em><em> </em><em>outcomes</em><em> </em>
P(without Red or Yellow) = 4/16 = 1/4
Hence, the probability of not landing on <em>yellow</em><em> </em><em>or</em><em> </em><em>red</em><em> </em><em>at</em><em> </em><em>all</em><em> </em>is 1/4.
