You spin the spinner shown two times. Each section of the spinner is the same size. Use this information to answer the question, giving a probability as a percent and rounding to the nearest tenth of a percent when necessary.


What is the probability that the spinner stops on 4 first and 1 second?

P(4 ∩ 1) = ?%

Respuesta :

Answer:

1/18 = 0.055% (repeating)

Step-by-step explanation:

4 = 2/12 = 1/6

1 = 4/12 = 1/3

1/6 • 1/3 = 1/18

The probability that the spinner stops on 4 first and 1 second is 5.55 %

What is percentage?

  • A relative avlue indicating one hundredth part of any quantity is called percentage.
  • Percentage is denoted by %

What is probability?

  • Probability refers to the chance of occurring of an event.
  • Probability is always ≤ 1

How to calculate  probability ?

Probability can be found by dividing the favourable cases by the total possible cases.

What are independent events?

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.

How to find the probability that the spinner stops on 4 first and 1 second ?

In the given figure,

  • There are  12 sections.
  • There are 2 4s
  • There are 4 1s

Total number of cases =12

  • For the first spin, the probability that the spinner stops on 4 is 2/12 = 1/6
  • For the second spin, the probability that the spinner stops on 1 = 4/12 = 1/3

Now we need to find P(4 ∩ 1).

  • We know that for independent events, the first occurrence donot depend on the other occurrences.

∴ P(4 ∩ 1) = P(4) x P(1)

               1/6 x 1/3 = 1/18 = 5.55 %
