Since Tina replaces the beads after each pick:
P(R,G,R)=(1/5)(1/5)(1/5)=1/125
From the given data, the value of N is equal to 5, The value of X is equal to 2. Since 38% of the consumers are comfortable with drone, this makes the value of P equal to 0.38. And now using the equation to find Q = 1 - P, where P is 0.38, we now get 1 - 0.38, therefore Q = 0.62. To summarize, N =5; X = 2; P = 0.38; Q = 0.62
" · " - times
" + " - sum
n - a number
0.5n - half a number
10 · (0.5n + 6) = 8 |use distributive property
(10)(0.5n) + (10)(6) = 8
5n + 60 = 8 |substract 60 from both sides
5n = -52 |divide both sides by 5
n = -10.4
