Problem Statement

• A spinner has 4 equal sectors with tour options Dubai, Seoul, Switzerland, and Paris.
• P(Seoul)=1/4  p(Paris)=1/4 P(Dubai)=1/4 p(Switzerland)=1/4
• What is the probability of landing on Seoul or Paris after spinning spinner?
  
• Write a function to return the probability

Note:

1. Display the probability in decimal rounded off to 2 decimal places
2. Hint: Addition Rule and Mutually Exclusive events

Function Description

Function Name: spinner()

1. Output:

• ans: Float - Denotes the probability

Answer:

from scipy import stats

def spinner():

    '''

    output: ans : Float

    '''

    #Write your code here

    seoul = 1/4

    paris = 1/4

    dubai = 1/4

    swit = 1/4

    

    prob = 1-(seoul+paris)

    #Assign the probability value to the variable ans

    # Round off to 2 decimal places

    ans=round(prob,2)

    

    return ans 

if __name__=='__main__':

    print(spinner())
