The students are either male or female and are also either domestic students or international students. From the results of the survey, the following probabilities are found: probability that a random student is female is 0.46 probability that a random student is an international student is 0.51 probability that a random student is a female international student is 0.21 probability that a random student is a female domestic student is 0.25 probability that a random student is a male international student is 0.30 probability that a random student is a male domestic student is 0.24 Let the events A and B be: Event A: a random student is female Event B: a random student is an international student a)An incomplete tree diagram for this scenario is presented below. Fill in the correct number of outcomes for each part of the tree. Give your answers as whole numbers. International Female Domestic International Male Domestic b)Find the probability that a random student from this group is not an international student given that they are female. Give your answer as a decimal to 3 decimal places. P(not B given A) = [6 marks]- 2 of 3 ID: MST.FET.P.CP.02.0040A A survey of 1,200 people is conducted to study how support for a new government initiative differs between people from rural and urban backgrounds. The 1,200 people are made up of 600 people from urban areas and 600 people from rural areas. Each person is asked whether or not they support the government proposal. The results of the survey show that 132 are rural and support the proposal; 468 are rural and do not support the proposal; 257 are urban and support the proposal; and 343 are urban and do not support the proposal. a)A tree diagram describing this situation has been drawn up, and some probabilities have been filled in. Complete the tree diagram for this scenario by filling in the appropriate probability for each part of the tree. Give your answers as decimals to 2 decimal places. Does support Rural 0.5 Doesn't support Does support Urban 0.5 Doesn't support Let the events A and B be: Event A: a random person from the survey is from a rural area Event B: a random person from the survey doesn't support the proposal b)Find the probability of A and B Give your answer as a decimal to 2 decimal places. P(A and B) = c)Find the probability of B given A. Give your answer as a decimal to 2 decimal places. P(B|A) = [2 marks]- 3 of 3 ID: MST.FET.P.CP.03.0020A For the random process of rolling two six-sided dice and recording the sum, let A and B be the events defined by: A: the result is an odd number B: the result is greater than 9 a)Calculate the probability of B given A.
