The tree diagram that represents the events is an illustration of probability and combination
<h3>The tree diagram</h3>To draw the tree diagram, we make use of the following representations:
- H for heads, T for tails,
- R for red, Y for yellow, and B for blue.
See attachment for the tree diagram.
<h3>The sample space and the outcomes</h3>From the tree diagram, the sample space is as follows:
S = {HR, HY, HB, TR, TY, TB}
<h3>The number of outcomes that represents "Toss a tail, spin yellow"</h3>This is represented as: TY
From the sample space above, we have:
TY = 1
Hence, the number of outcomes that represents "Toss a tail, spin yellow" is 1
<h3>The probability</h3>We have:
TY = 1
Sample size = 6
Hence, the of tossing tails and spinning yellow is 1/6
