Question 755053: Can You please help me with this question and let me know if I'm doing it correctly.
What is wrong with: the probabilty that a student will score high on this exam is 0.43, while the probability that he will not score high is 0.47? Show all work.
Answers That I worked out - not sure if I did it correctly.
P(will score high)= 0.43/0.90 = 0.478
P(will not score high)= 0.47/0.90 = 0.522
Thank you very much jammie

-------
P(sill score) + P(will not score) = 1.00
But you have
0.43 + 0.47 = 0.90
---
the sum of the probabilities must be 1.00
