Question

spin the spinner below. suppose that you win a prize if it lands on green. 7 green (success) 3 pink (failure) what is p, the probability of success? what is 1 - p, the probability of failure?

Explanation:

Step1: Recall probability formula

The probability of an event $p=\frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}$.

Step2: Calculate total number of outcomes

The total number of sections on the spinner is $7 + 3=10$.

Step3: Calculate probability of success $p$

The number of green (success) sections is 7. So $p=\frac{7}{10}=0.7$.

Step4: Calculate probability of failure $1 - p$

$1 - p=1-0.7 = 0.3$.

Answer:

$p = 0.7$
$1 - p=0.3$
