Answer:
b=4
Step-by-step explanation:
4b + 5 = 1 + 5b
Subtract 4b from each side
4b-4b + 5 = 1 + 5b-4b
5 =1+b
Subtract 1 from each side
5-1 = 1-1+b
4 =b
Im pretty sure it would be 0.2
0789 is the smallest
9870 is the largest
Answer:
P(Y=r) = 
Step-by-step explanation:
Given that a bag contains 1 red, 3 green, and 5 yellow balls. A sample of four balls is picked, with replacement
When balls are picked with replacement, each time the ball picked up does not depend on the previous outcomes.
Thus given y=2 will not affect the pdf of G
In G, Y no of yellow balls can take values as 0,1,2,3,4
Prob of drawing a yellow ball each time = 5/9
Y = no of yellow balls is binomial with n =4 and p = 5/9
P(Y=0) = 
In general,
P(Y=r) =
