Answer:
a. =
b.
Step-by-step explanation:
a) When <em>n </em>is even, then it is divisible by 2. Because of this, you can write:
b) When <em>n </em>is odd, then <em>n - 1 </em> is even. This would make it divisible by 2, and there would be a remainder of 1, so we can write:
Answer:
B. The probability of getting a red convertible is 0.10.
Step-by-step explanation:
Independent events:
Two events, A and B, are independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:
In this question:
Event A: Red car -> 0.25 probability
Event B: Convertible car -> 0.4 probability
Independent if:
The probability of getting a red convertible car is:
Thus, the correct answer is given by option B.
