A new surgery is successful 70% of the time. Suppose you choose a random sample of 10 such surgeries. a. Write the values of the parameters: n H .0 II .D II b. Identify the distribution of the random variable X using the notation shown in lecture: For parts c and d, circle the values that make up the event, write the probability question mathematically, write the Tl83/84 entry used to find the probability, and round your nal answers to 3 decimal places. c. Find the probability at least 6 were successful. 0 1 2 3 d. Find the probability that more than 4 were successful. 0 1 2 3 4 5 6 7 8 9 10
