Answer:
b ) the intersection of two events
Step-by-step explanation:
Gary and Steve are both hosting . There are 50 buttons total, 15 buttons are blue and 27 buttons are red. Gary puts all of the buttons into a bag. Steve and Gary both want to wear red buttons.What is the probability ? To solve this problem, you need to understand the Multiplication Rule of Probability.This probability means to find the probability of the intersection of two events, multiply the two probabilities.
Probability of two events occurring that is called intersection of two events. There are two different set of events , called independent and dependent events.
Independent events event is not affected by a previous event.
A dependent event is when one event influences the outcome of another event . To find the intersection of two events, whether they are independent or dependent, multiply the two probabilities together.
Answer:
if im understanding right, answer is 207
Step-by-step explanation:
1000 + 1000 = 2000
7 x 10 = 70
2070 / 10 = 207

Answer: length = 7 feet's
Width = 6 feets
Step-by-step explanation:
Perimeter of a rectangle is the distance round the rectangle.
Perimeter of rectangle is expressed as
2(length + width)
The perimeter of the given rectangle is 26 feet. Therefore
2(L + W) = 26
Dividing by 2,
L+W = 13
The area of a rectangle is expressed as length × width
The given area is 42 square feet. Therefore,
L×W = 42
Substituting L = 13 - W into LW = 42, it becomes
W(13-W) = 42
13W - W^2 = 42
W^2 -13W + 42 = 0
W^2 -7W - 6W + 42 = 0
W(W - 7) - 6(W - 7) = 0
(W-6)(w-7)=0
W-6 = 0 or W-7=0
W=6 or W = 7
L= 13-6 or L= 13-7
L= 7 or L = 6
