The probability of winning is 4/13.
These two events are not mutually exclusive; this means they can happen at the same time. For two events that are not mutually exclusive,
P(A or B) = P(A) + P(B) - P(A and B)
This gives us
P(spades or Ace) = P(spades) + P(Ace) - P(spades and Ace)
There are 13 spades out of 52 cards.
There are 4 aces out of 52 cards.
There is 1 card that is a spade and an ace out of 52 cards.
13/52 + 4/52 - 1/52 = 16/52 = 4/13
Based on the graph, the slope is -3, and the y-intercept is 1. So your equation should be:
y = -3x + 1
The answer is C
y + 2 = -3(x - 1)
y + 2 = -3x + 3
y = -3x + 1
A. 5500x(1+5%)=$5775
b. 5775x(1+5%)=$6063.75
Those are your answers.
