Conditional probability About 25 of the population watches the evening television news coverage as well as the soap operas. If 75 of the population watches the news, what percent of those who watch the news also watch the soaps?Conditional probability The probability of rain today is 0.40. If it rains, the probability that Cameron will forget his raincoat is 0.70. Find the probability that Cameron will get wet.What is an experiment? Give two examples.What is meant by the sample space of an experiment?Describe how to determine the probability of an event.Explain the Multiplication Property of Probabilities.If P(AB)=0.7, is it possible that P(BA)=0.6? ExplainIs it possible that P(AB)=P(A)? Explain.Determine if the statement is true or false. If the statement is false, then correct it and make it true. The probability that an event occurs can be a negative number.Determine if the statement is true or false. If the statement is false, then correct it and make it true. The probability of a certain event is 0.Determine if the statement is true or false. If the statement is false, then correct it and make it true. The probability of an impossible event is 1.Determine if the statement is true or false. If the statement is false, then correct it and make it true. If the probability that you will graduate is 0.63, then the probability that you will not graduate is -0.63.Determine if the statement is true or false. If the statement is false, then correct it and make it true. Events that cannot occur simultaneously are called mutually exclusive events. If one card is randomly selected from a deck of cards, drawing a jack or a queen would be mutually exclusive events.Determine if the statement is true or false. If the statement is false, then correct it and make it true. Events that can occur simultaneously are called non-mutually exclusive events. If one card is randomly selected from a deck of cards, drawing a jack or a heart would be non-mutually exclusive events.Determine if the statement is true or false. If the statement is false, then correct it and make it true. The probability of a couple having four boys is 12 because the probability each time of having a boy is 12.Determine if the statement is true or false. If the statement is false, then correct it and make it true. If the probability of a couple of five girls is 132, then the probability of having five boys is 3132.1E2E3E4E5E6E7E8E9EFind the required term of each expansion. 2x-y5; 3rd term11E12E13E14E15E16EEvaluate each expression. k=143k2Evaluate each expression. k=110619E20E21E22E23E24EFind three arithmetic means between 2 and 8.26E27E28EFind the sum of the first 40 terms in each sequence. 6,-1,-8,Find the sum of the first 40 terms in each sequence. 12,-32,-72,Find the required term of each geometric sequence. 81,27,9,; 11th termFind the required term of each geometric sequence. 2,6,18,; 9th termFind the required term of each geometric sequence. 9,92,94,; 15th termFind the required term of each geometric sequence. 8,-85,825,; 7th termFind three positive geometric means between 2 and 8Find four geometric means between -2 and 64.Find the positive geometric mean between 4 and 64.Find the sum of the first 8 terms in each geometric sequence. 81,27,9,39E40E41E42E43E44E45E46E47E48E49E50E51EInvestment problem If Landon invests 3000 in a 6-year certificate of deposit at the annual rate of 7.75, compounded daily, how much money will be in the account when it matures?53E54EVerify the following formula for n=1,n=2,n=3, and n=4: 13+23+33++n3=n2n+12456E57E58E59E60E61E62E63E64E65E66E67EEvaluate each expression.
