hello i need help with these statistic questions

question 1

According to a survey, the distribution of graduate science students in doctorategranting institutions is shown to the right. Frequencies are in thousands. graduate science student who is attending a doctorate-granting institution is selected at random. Complete parts a through c. 3. Determine the probability that the field of the student obtained is psychology. (1142' (Round to three decimal places as needed.) b. Determine the probability that the field of the student obtained is physical or social science. 0.390' {Round to three decimal places as need ed.) c. Determine the probability that the field of the student obtained is not computer science. 0360' (Round to three decimal places as needed.) Field Frequency Physical sciences 34.1 Environmental sciences 10.5 Mathematical sciences 17.2 Computer sciences 43.6 Agricultural sciences 12.8 Biological sciences 63.1 Psychology 46.2 Social sciences 88.8An ordinary deck of playing cards has 52 cards. There are four suitsspades, heartsI diamonds, and clubswith 13 cards in each suit. Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. LetAdenote the event that a 1D is chosen. Find the probability that a 1D is chosen. and express your answer in probability notation. The probability that a 10 is chosen is = (Type an integer or a decimal. Round places as needed.) [A AP FA
