13. Assume that 11% of people are left-handed. If 4 people are selected at random, find the probability of each outcome described below. a) Find the probability that the first lefty is the third person chosen. 0.0871 (Round to four decimal places as needed.) b) Find the probability that there are some lefties among the 4 people. 0.3726 (Round to four decimal places as needed.) c) Find the probability that the first lefty is the third or fourth person. 0.1647 (Round to four decimal places as needed.) d) Find the probability that there are exactly 3 lefties in the group. (Round to four decimal places as needed.) e) Find the probability that there are at least 2 lefties in the group. (Round to four decimal places as needed.) f) Find the probability that there are no more than 2 lefties in the group. (Round to four decimal places as needed.)

If we assume that the probability of a person being left-handed is p, then the probability of this event is (1-p)^2 * p. Show moreā¦

Assume that 14% of people are left-handed. If 4 people are selected at random, find the probability of each outcome described below: a) Find the probability that the first lefty is the second person chosen. (Round to four decimal places as needed.) b) Find the probability that there are some lefties among the 4 people. (Round to four decimal places as needed.) c) Find the probability that the first lefty is the third or fourth person. (Round to four decimal places as needed.) d) Find the probability that there are exactly 3 lefties in the group. (Round to four decimal places as needed.) e) Find the probability that there are at least 2 lefties in the group. (Round to four decimal places as needed.) f) Find the probability that there are no more than 2 lefties in the group. (Round to four decimal places as needed.)

Assume that 13% of people are left-handed. If we select 10 people at random, answer the following questions: a. What is the probability that there are exactly 3 lefties in the group? . (Use 3 decimal places.) b. What is the probability that there are at least 3 lefties in the group? . (Use 3 decimal places.) c. Find the expected number of right-handers in the group. d. Find the standard deviation of the number of right-handers in the group. (Use 3 decimal places.) e. What is the probability that they are not all right-handed? . (Use 3 decimal places.) f. What is the probability that there are exactly 5 righties and 5 lefties? . (Use 4 decimal places.) g. What is the probability that the majority is right-handed?

About $12 \%$ of all individuals write with their left hands. A class of 130 students meets in a classroom with 130 individual desks, exactly 14 of which are constructed for people who write with their left hands. Find the probability that exactly 14 of the students enrolled in the class write with their left hands.
