The probability that a student has a visa card (event v) is .73. the probability that a student has a mastercard (event m) is .14. the probability that a student has both cards is .03. (a) find the probability that a student has either a visa card or a mastercard. (round your answer to 2 decimal places.)

The probability that a student has either a Visa card or a MasterCard is 0.84.        

Step-by-step explanation:

Given : The probability that a student has a Visa card (event V) is 0.73. The probability that a student has a MasterCard (event M) is 0.14. The probability that a student has both cards is 0.03.

To find : The probability that a student has either a Visa card or a MasterCard ?

Solution :

The probability that a student has a visa card(event V) is P(V)= 0.73

The probability that a student has a MasterCard (event M) is P(M)= 0.14

The probability that a student has both cards is

Probability that a student has either a Visa card or a Master Card is given by,

Therefore, the probability that a student has either a Visa card or a MasterCard is 0.84.

You cannot buy it.

Step-by-step explanation:

$450 with a 20% percent discount would be $360

Add in a sales tax of 5.25%, and it amounts to $549 in total.

Since you only have $400, you cannot buy the bike.
