if you spin the spinner 5 times, what is the best prediction possible for the number of times it will land on green? times

Answer

Explanation:

Step1: Determine probability of landing on green

Assume the spinner is divided into 8 equal - sized sections and 2 are green. The probability $P$ of landing on green in a single spin is $P=\frac{2}{8}=\frac{1}{4}$.

Step2: Use expected - value formula

The expected value $E$ of the number of times an event occurs in $n$ trials is $E = n\times P$. Here, $n = 5$ (number of spins) and $P=\frac{1}{4}$. So $E=5\times\frac{1}{4}=\frac{5}{4}=1.25$.

Answer:

$1.25$
