Hey! :)
Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.4 : 5 ( = 9 too little )8 : 10 ( = 18 just right)12 : 15 ( = 27 too much)So per necklace, 8 yellow beads and 10 blue beads would be needed.
Hope this helps! :)

Answer:
1/3
Step-by-step explanation:
perpendicular lines have slopes that are opposite reciprocals
The probability of obtaining a 1 is 1/13, so the probability of not getting a 1, that is, the probability of getting a ball different from 1, is 1- (1/13)=12/13, which is 0.923
