The probability that a student has either a vise card or a master card is: 0.72
Step-by-step explanation:
Given that
Probability that a student has a vise card = P(V) = 0.65
Probability that a student has a master card = P(M) = 0.20
Probability that a student has both = P(V∩M) = 0.13
We have to find the probability of V OR M
The probability is given by:
[tex]P(V\ or\ M) = P(V) + P(M) - P(V\ and\ M)[/tex]
Putting the values,
[tex]P(V\ or\ M) = 0.65+0.20-0.13\\P(V\ or\ M) = 0.72[/tex]
Hence,
The probability that a student has either a vise card or a master card is: 0.72
