The probability that a student has a visa card (event v) is .63. the probability that a student has a mastercard (event m) is .11. 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.) probability .77 .77 incorrect (b) in this problem, are v and m independent

a)  The probability that a student has either a Visa card or a MasterCard is 0.71.  

b) V and M are not independent.

Step-by-step explanation:

Given : The probability that a student has a Visa card (event V) is 0.63. The probability that a student has a MasterCard (event M) is 0.11. The probability that a student has both cards is 0.03.

To find :

a) The probability that a student has either a Visa card or a MasterCard ?

b)  In this problem, are V and M independent ?

Solution :

The probability that a student has a visa card(event V) is P(V)= 0.63

The probability that a student has a MasterCard (event M) is P(M)= 0.11

The probability that a student has both cards  is

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

The probability that a student has either a Visa card or a MasterCard is 0.71.

b) Two events, A and B, are independent if

For V and M to be independent the condition is satisfied,

Substitute the values,

So, V and M are not independent.
