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:
![P(V\ or\ M) = P(V) + P(M) - P(V\ and\ M)](https://tex.z-dn.net/?f=P%28V%5C%20or%5C%20M%29%20%3D%20P%28V%29%20%2B%20P%28M%29%20-%20P%28V%5C%20and%5C%20M%29)
Putting the values,
![P(V\ or\ M) = 0.65+0.20-0.13\\P(V\ or\ M) = 0.72](https://tex.z-dn.net/?f=P%28V%5C%20or%5C%20M%29%20%3D%200.65%2B0.20-0.13%5C%5CP%28V%5C%20or%5C%20M%29%20%3D%200.72)
Hence,
The probability that a student has either a vise card or a master card is: 0.72

Answer: Scale Factor = 3
Step-by-step explanation:
The top side of the blue triangle is equal to 2 and the top side of the red triangle is equal to 6. Therefore you hav to divide 6 by 2 to give you the scale factor which is 3. (Sorry I do not know if zoom factor is the same as scale factor)
sorry it took me so long to answer this!!
Yes, the answer would be tan y.
