The probability that a student has a visa card (event V ) is .73. The probability that a student has a Master card (event M) is .14. The probability that a student has either a Visa or Master card is .03.

Find the probability that a student has either a visa or mater card

probability

The probability that a student has either a visa or master card is 0.84.

It is calculated as follows:

Step-by-step explanation

The probability that a student has a Visa card (event V) = 0.73.

The probability that a student has a Master card (event M) = 0.14.

The probability that a student has both cards = 0.03

Thus we have,

P(V) = 0.73

P(M) = 0.14

P(V and M) = 0.03

Therefore, the probability that a student has either a Visa card or a Master card is given by:

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

=0.73 + 0.14 - 0.03

=0.87 - 0.03

= 0.84

P(V or M) =0.84
