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.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
