Question

Can you help me with my work

Answer 1

The number of yellows counter is given by the function:

`f(n)=128-(1)/(2)n`

if we want this to be exactly 1 counter we equate the function to 1 and solve for n:

`\begin{gathered} 128-(1)/(2)n=1 \\ 128-1=(1)/(2)n \\ (1)/(2)n=127 \\ n=127\cdot2 \\ n=254 \end{gathered}`

Therefore, the number of trials will be 254.
