Use the following table to find the probability. MaleFemaleWrite with left hand5538Do not write with left hand95130 If one the subjects is randomly selected, find the probability that the person is a male or do not write with left hand.If one of the subjects is randomly selected, find the probability that the person is a male given that the person writes with left hand.If two subjects are randomly selected without replacement, find the probability that both female and do not write with left hand.

1. Consider the following table for necessary calculations. Male Female Total Write with left hand 55 38 93 Do not write with left hand 95 130 225 Total 150 168 318 Total number of persons is 318. The total number of male is 150. The total number of person, who do not write with left hand is 225. The total number of persons, who are male and do not write with left hand is 95. Thus, if one the subjects is randomly selected, the probability that the person is a male or do not write with left hand, P(Male or Do not write with left hand) = P(Male) + P(DO not write with left hand) – P(Male and Do not write with left hand) = 150/318 + 225/318 – 95/318 = 280/318 = 0.8805. 2. The total number of person, who write with left hand is 93. The total number of persons, who are male and write with left hand is 55. If one of the subjects is randomly selected, the probability that the person is a male given that the person writes with left hand is, P(Male | Write with left hand) = P(Male and write with left hand)/P(Write with left hand) = (55/318)/(93/318) = 0.5914. 3. The total number of persons, who are female and do not write with left hand is 130. The probability that a randomly selected subject, who is female and do not write with left hand is 130/318. The selection is done by without replacement. Now, there are remaining 317 total subjects and remaining 129 persons, who are female and do not write with left hand. Hence, the probability that another randomly selected subject, who is female and do not write with left hand is 129/317 Thus, If two subjects are randomly selected without replacement, the probability that both female and do not write with left hand, (130/318)(129/317) = 0.1664.
