Question

3 points each nts. Pick two students randomly, 1. In a Math 2526 class, there are 10 female and 15 male students. PICK the probability that both are male students is: - 0.55 a) 0.25, b) 0.35, c). 0:35, d). 0.45 2. In a Math 2526 class, there are 10 female and 15 male students. Among 10 got grade A. Among 15 male students, also 3 got grade A. le students. Among 10 female students, 3 Let A= 'pick one student randomly from the class, his/her grade Is A M='pick one student randomly from the class, this student is male Then, the conditional probability of P(MIA) is: a). 0.50, b). 0.20, c). 0.23, d). 0.30 3. The following data indicate about Type of blood and aggressiveness behavior. Type of blood A other total Aggressive 56 24 30 110 Not aggressive 120 226 80 426 total 176 250 110 536 Let G = person is aggressive, A = person is type A blood.
