Question

if gerald spins the spinner 630 times, approximately how many times should he expect the spinner to land on 3

Answer 1

The spinner is rotate 630 times.

Since the spinner is distribute into 5 numbers i.e 1, 2, 3, 4 & 5

Probability of getting the spinner land on 3 at first spin

`\begin{gathered} \text{Probability to land on 3, at first spin =}(1)/(5) \\ \text{ So,} \\ \text{Probability to land on 3, at 630 times =}630*(1)/(3) \\ \text{Probability to land on 3, at 630 times =}(630)/(3) \\ \text{Probability to land on 3, at 630 times =}210 \end{gathered}`

There are 210 expected times that the spinner land on 3.

Answer : 210 times
