Which statement is correct?
1 answer:
Well... the two rectangles are in the picture below, those are their coordinates
so, you can pretty much see how long one side is, since you can simply count the units on the grid
running a tests on them.... hmmm they'd be similar is the length of the corresponding sides on each figure, give the same ratio

Answer:
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.
