Let's call the aces for hearts, diamonds, clubs and spades. So,
are red and [ted] c, s[/tex] are black.
Since the first card is replaced, the two picks are identical. This means that the sample space is given by all the possible couple
There are 16 such couples (we have four choices for the first card, and the same four choices for the second card). Now let's compute the odds in our favour to deduce the probability of winning:
If we want a player to draw two card of the same colour, the following couples are good:
so 8 possible couples over 16. This means that the probability that a player draws two cards of the same color is 8/16 = 1/2.
Similarly, the probability of drawing a red ace first and then a black ace is represented by the following couples:
which are 4 over the same 16 as above, thus leading to a probability of 4/16 = 1/4.
Answer:
slope = -
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = 3 (x + 4) ← is in point- slope form
with slope m = 3
The diagonals of a square are perpendicular to each other.
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
Thus the slope of FH is -
Answer:
<h2>71.8%</h2>Step-by-step explanation:
The shape described in question is a square overlaid with two quarter circles(a semi circle)
Area of the figure = Area of the square + area of the semi circle
Area of the figure =
L = length of a side of the square = 12in
r is the radius of the semi circle = 6in
Area of the figure =
Area of the figure = = 200.55in²
Since the shaded portion is a square;
percent of the total area is shaded = area of the square/total area * 100%
percent of the total area is shaded = 144/200.55* 100
percent of the total area is shaded= 71.8%
