Consider a fair spinner with five sections labeled 1, 2, 3, 4, and 5. The probability for landing on region 1 is one-fifth, region 2 is one-eighth, region 3 is one-third, and regions 4 and 5 have unknown probabilities. The spinner can only land on one section at a time.
Describe the possible probabilities of landing in region 4 or region 5. Draw a diagram to assist your explanation.
Can someone help me figure out how to complete this problem?
Okay so apparently my way is incorrect of finding p4 and p5. HOW do I determine what p4 and p5 are? I will have to create a pie chart showing all 5 of my regions .. so I would think my denominator would be a whole number (2,3,4,etc) .. I am confused on the 42/120?
Okay, I will just have to ask my instructor for further detail. If there is no way to know exactly what p4 and p5 are then why does my question ask to find the probabilities of it landing on p4 and p5. So apparently the question cannot be answered if there is not a way for all 5 parts to equal 1.
