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%2F22 you can choose any of these marbles.


Therefore, the probability to choose the red marble is  6%2F22 = 3%2F11.


The probability to choose one green marble is  5%2F22.


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