I’m pretty sure this is right but I did my best lol sorry
Probability that the first card is not a club is 1 minus probability that it is a club. i.e. 1 - 1/4 = 3/4
Probability that the second card is not a heart is 1 minus probability that it is a heart. i.e. 1 - 1/4 = 3/4
Probability that the first card is not a club AND the second card is not a heart is 3/4 x 3/4 = 9/16

Answer: A
Step-by-step explanation: So, first of all, this is a linear graph, which is represented by the equation y = mx + b.
b = y-intercept. The y-intercept is the point in which the line crosses the y axis. Assuming this graph has units that go up by 1, the y- intercept for this line is 2, which eliminates choices B and C.
This graph is going down, which means it is negative, so the format should be -mx + b, which is answer choice A. Hope this helps! :)
Answer:
Step-by-step explanation:
<u>Given</u>
a)
- DC /AB = 3/2 ⇒
- DC = 3/2AB = 3/2p
b)
- BC = AD + (DC - AB)
- BC = q + (3/2p - p) = q + 1/2p
