Answer:
c 0.76
Step-by-step explanation:
Red or Black (A)= 30
Missing cap (B)= 20
Red or black and missing cap (A&B) = 12
Total number of markers = 50
The total number of markers that are red or black or is missing its cap is:
[tex]n= A+B-(A\cap B)=30+20-12=38[/tex]
The probability of picking of those markers randomly is:
[tex]P=\frac{38}{50}=0.76[/tex]
The probability that a randomly selected marker is red or black or is missing its cap is 0.76.
