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:

P(V\ or\ M) = P(V) + P(M) - P(V\ and\ M)

Putting the values,

P(V\ or\ M) = 0.65+0.20-0.13\\P(V\ or\ M) = 0.72

Hence,

The probability that a student has either a vise card or a master card is: 0.72
