Question

Rina spins the spinner below 30 times. A success occurs when the spinner lands on a number that is greater than 6. What is the probability of a success and a failure for this experiment?

Answer 1

B. P(success)=1/4,P(failure)=3/4 

Answer 2

Answer:

Success: 1/4

Failure: 3/4

Step-by-step explanation:

A  success occurs when  the spinner lands on a number that is greater than 6 that is we will take the numbers which are greater than 6 but less than 30 as the spinner is spinned below 30 times.

Therefore the total number of outcomes will be: 30-6= 24

Hence, the probability of a success of the experiment will be: $\frac{Number of outcomes in which success occurs}{Total number of outcomes}$

=$\frac{6}{24}$

=$\frac{1}{4}$

the probability of a failure of the experiment will be= 1- Probability of a success of the experiment

=$1-\frac{1}{4}$

=$\frac{3}{4}$
