Answer: 0.3077
Explanation: In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).
Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 7.
With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).
Our denominator here is 52 - the number of cards from which we can pull 1.
Our numerator is both all the diamonds, 13 cards, and all the sevens, 4 cards, but we need to subtract 1 to account for the double counting of the 7 of diamonds.
In all we get: 13+4−1/52=16/52=4/13≈0.3077
Hope this helps... Stay safe and have a great day/night!!!

Answer:
The coordinates of R is (-3,8)
Step-by-step explanation:
The formula for the midpoint of a line segment is;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
In this case, we have (x,y) = (4,3)
and we also have (x1,y1) = (11,-2)
what we do not have is (x2,y2)
From the question, we have that;
(11 + x2)/2 = 4
11 + x2 = 2(4)
11 + x2 = 8
x2 = 8-11
x2 = -3
Also;
(-2 + y2)/2 = 3
-2 + y2 = 2(3)
-2 + y2 = 6
y2 = 6 + 2
y2 = 8
So the coordinates of R is (-3,8)
Answer:
The probability of getting a peach or an apple is 2/3.
Step-by-step explanation:
There are two peaches and four apples, so six fruits we want to know the probability of getting, and there are also three pears, which means we have nine fruits total. The chance of getting an apple or a pear is six out of nine, which simplifies to two out of three.
