Question 1116646
.
<pre>
I will help you to answer only one section: section c.


The total number of marbles in the jar initially is  6+5+8+3 = 22.


With the equal probability of {{{1/22}}} you can choose any of these marbles.


Therefore, the probability to choose the red marble is  {{{6/22}}} = {{{3/11}}}.


The probability to choose one green marble is  {{{5/22}}}.


Based on this, by analogy, answer regarding blue marble and yellow marble on your own.
