Answer:
C
Step-by-step explanation:
If two events are independent, the probability of both happening are:
P(A and B) = P(A) × P(B)
In this case, if rain and lightening were independent:
P(rain and lightening) = P(rain) × P(lightening)
P(rain and lightening) = 0.45 × 0.45
P(rain and lightening) = 0.2025
However, we're told that P(rain and lightening) is 0.25, not 0.2025.
Since 0.2025 ≠ 0.25, the events are not independent, so they are dependent.
One answer could be, 2 4/6 and 3 2/6
No.
4 yards is not greater than 13 ft.
Answer:
5
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(x) = 2x -1
f(3) = 2·3 -1 = 6-1
f(3) = 5
X + y = 12
Xy = - 28
Therefore the answer is B: - 2, 14
