Question

This spinner has 3 equal sections labelled 2, 5 and 7.How many times would you expect to spin a oddnumber in:30 spins? 150 spins? 240 spins?

Answer 1

Given data:

The numbers in the spin are 2, 5 and 7.

The expression for the probability of odd number is,

`P(O)=(2)/(3)`
`\begin{gathered} E=30*(2)/(3) \\ =20 \end{gathered}`

Thus, the number of times spin land on odd number are 20 when we spin 30 times.
