the probability that a student has a Visa card (event V) is .65 The probability that a student has a mastercard (event M) is .20
1 answer:
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:
Putting the values,
Hence,
The probability that a student has either a vise card or a master card is: 0.72

To rewrite these equations in standard form you need to understand that standard form looks something like this Ax+By=C, now obviously there will be variations like </span>Ax-By=C or -Ax+By=C, etc..., but for these expressions, they would look like this:
<span>1. -8y + 0x = 37
2. 14x </span>+ 4y<span> = -18
3. x + </span>

4. 13x + 0y = -25
