The probability of a student getting A;B;C;and D grade are 0.35,0.25,0.35,0.05 respectively. Then find the probability of a student getting at most C grade
the probability of a student getting at most C grade = probability of getting either C grade or D grade
= 0.35+0.05
=0.40
hope this helps you
= 0.35+0.05
=0.40
hope this helps you
