To find the GCF, first you must factor the 2 or more numbers. The GCF is the highest factor the numbers have in common. for example: you have 12 and 8. If you factor out the numbers for 12, you get 1,2,3,4,6,12 For 8, you get: 1,2,4,8 the GCF of this pair is 4 because it is the highest number that goes into both 8 and 12. To find the LCM, you must find the first number that was multiplied and it must be the same. lets take 3 and 5. Multiply 3 by as many numbers you can think of. For now, lets just go up to 10. 3, 6, 9, 12 15, 18, 21, 24, 27, 30 now to the same for 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 in both 3 and 5, the first set of numbers that match in 30- therefore the LCM of 3 and 5 in 30. I hope this helps!
This is question of probability finding using bayes theorem It is used to calculate probability of two competing statements now p(m) = .55 p(~m)= .45 now for basketball for male p(b|m)=.30 and for female p(b|~m)=.20 so by bayes theorem p(m|b)=p(b|m)*p(m)/(p(b|m)*p(m)+p(b|~m)*p(~m)) so answer is E (.55)(.30) / (.55)(.30) + (.45)(.20)
