Question

Use the spinner below to calculate the following probability round solution to 2 decimal faces

Answer 1

Part 1

Probability of 7 is

P=1/12

Probability of 4 is

P=1/12

so

Probability of 7 or 4 is equal to

P=(1/12)+(1/12)

P=2/12 -----> P=1/6 -----> P=0.17

Part 2

Probability of a even number

Remember that the even numbers in the spinner are -----> 2,4,6,8,10 and 12

so

P=6/12 ------> P=0.50

Part 3

A multiple of 3 --------> 3,6,9 and 12

so

P=4/12 ------> P=0.33

Part 4

is an example of --------> clasical probability
