Suppose a jar of 50 marbles consists of 10 red marbles, 12 blue marbles, 5 green marbles, 4 black marbles, 1 white marble, 9 pink marbles, 3 orange marbles, and 6 yellow marbles.    If you were to randomly select one marble from the jar, what is the probability that the marble would be red or orange? Type your answer as a decimal rounded to 2 decimal places. For example if you thought the answer was 0.12345 then you would type in 0.12.

The CBEST is a test that individuals in California must take before they can become substitute teachers at the K-12 level. One portion of the exam is devoted to mathematics and it consists of 50 multiple choice questions that each have 5 possible options. Suppose Jim took the CBEST test and decided to randomly guess on all 50 questions. Use this information to answer the following question.    What is the probability that Jim gets no less than 9 correct? Make sure to type in your answer as a decimal rounded to 3 decimal places. For example, if you thought the answer was 0.54321 then you would type in 0.543.
