Question

If a spinner has 10 equal-sized sections, which of the following will be false? a. P(1) = 10% c. P(2) = 10% b. P(not 1) = 10% d. P(not odd) = 50%

Answer 1

Answer:

P(not 1) = 10%

If there are 10 sides, then the P(not 1) is 90%.

Answer 2

Probabilities are used to determine the chances of events

The false statement is b. P(not 1) = 10%

The sections in the spinner is given as:

Section = 10 equal-sized section

The above means that:

P(n) = 10% where n is between 1 and 10 (inclusive)

The probabilities of odd and even are also represented as:

P(Odd) = P(Even) = 50%

Hence, the false statement is b. P(not 1) = 10%
