For the first question, the chance of rolling a six is a 1/6 chance because there is one six and six different sides that could be rolled. As a percent, it would be 16.6 %. The probability of rolling an odd number on the second roll would be a 3/6 chance, which as a percent is 50 %. For the second question, both probabilities are 33 % because in both instances you are drawing three cards from nine total, so it would be 3/9. For the third question, the probability of drawing a blue marble is 3/5, because there are three blue marbles and five total marbles. As a percent, this is 60 %. Following this up with a green marble would be 2/4, because there are now 2 green marbles and four total marbles. One of the marbles was not replaced, so we have one less marble. 2/4 as a percent  is 50%.

Answer:

y = 39

Step-by-step explanation:

550 x \pi = \pi r^{2} x 11 + y

550 x \frac{7}{22} = \frac{7}{22} x 11 x 11 + y

550 x \frac{7}{22} x \frac{22}{7} = 11 x 11 + y

550 = 11 x 11 + y

\frac{550}{11} = \frac{11}{11} x 11 + y

50 = 11 + y

50 - 11 = y

39 = y
