Question

A three section spinner shown, the three diagram shows the possible outcomes for the town spins.What is the probability of spinning the same number in both spins?

Answer 1

`Pr = (1)/(3)`

Explanation:

Given

`n = 9` --- total outcomes

Required

The probability of same number in both spins

The list of same outcomes are:

`L = \{(1,1),(2,2),(3,3)\}`

`n(L) = 3` ----- The number of outcomes

So, the probability is:

`Pr = (n(L))/(n)`

`Pr = (3)/(9)`

`Pr = (1)/(3)`
