Question

You spin the spinner. Are the possible outcomes 1,2, and 3 equally likely show probabilities for each circle yes or no

Answer 1

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:

$P(1)=\frac{3}{12}=\frac{1}{4}$

The possible outcome for #2 is as follows:

$P(2)=\frac{5}{12}$

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

$P(3)=\frac{4}{12}=\frac{1}{3}$
