Answer: (a) Independent events , (b) 0.00075
Step-by-step explanation:
Since we have given that
Number of coins = 218
Number of rare Indian pennies = 6
Let Event A: When one of the 218 coins is randomly selected, it is one of the 6 Indian pennies.
Event B : When another one of the 218 coins is randomly selected (with replacement), it is also one of the 6 Indian pennies.
As we know that
(a) so, they are independent events as there is a condition of 'with replacement'.
(b) P(A and B) is given by
Hence, (a) Independent events , (b) 0.00075
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2.5) and (x₂, y₂ ) = (2, 1) ← 2 points on the line
m = =
=
Note the line crosses the y- axis at (0, - 2.5) ⇒ c = - 2.5 = -
y = x -
→ A
