that an organization was trying to create a team of eight edge of a particular manufacturing (1) Suppose that an organization from different departments who had knowl of which 10 are from the design department.If knowledge of were to be selected at random, process. A total of 50 people within the organization have k oobability that the team will contain at least two will contain at least two members from the design department? (a) 0.4967 (b) 0.5095 (c) 0.6783 (d) 0.7482 (e) 0.8567 (2) The random variables x and Yhave a joint density function given by 0, elsewhere wa he u oyx Please answer all What is the value of P3Y (a) 0.333 (b) 0.750 (c) 0.375 (d) 0.625 (e) 0.575 questions 1-4, show work will rate 100% (3) In an experiment a digit is randomly selected from seven digits 1,2,3,4, 5, 6, and 7. Selection of an even digit is as likely as the selection of an od digit. A isthe event that a randomly selected numberis greater than 3,B 2, and Cis the event that a randomly selected number is the event that a randomly selectednumberis greater than is less than or equal to 3.

Solution:-
1) The probability that the team will contain atleast two members from design department is 0.4967.
N = 50, x = 10
p = 10/50
p = 0.20
n = 8
By applying binomial distributiion:-
P(x,n) = nCx*px*(1-p)(n-x)
P(x > 2) = 0.4967
