EXPLANATION

The probability for 1 , 2 and 3 are not equally likely because the fill different dimensions on the spinner.

The equation for the probability is as follows:


P(x)=\frac{Number\text{ of favourable outcomes}}{\text{Total numbers of possible outcomes}}

We need to divide the spinner in same divided parts:

#1 Parts: 3

#2 Parts: 5

#3 Parts: 4

Number of total parts = 12

The possible outcome for number 1 is:


P(1)=(3)/(12)=(1)/(4)

The possible outcome for #2 is as follows:


P(2)=(5)/(12)

The possible outcome for #3 is as shown as follows:


P(3)=(4)/(12)=(1)/(3)
