Given:
The two statements.
To find:
The probability of an impossible event.
The probability of a certain event.
Solution:
Formula for probability is:
For an impossible event, the possible favorable outcomes is 0. So,
For a certain event (sure event), the possible favorable outcomes is equal to total number of outcomes. So,
Therefore, an event that is impossible has probability 0 and an event that is certain has probability 1.
The way I like to do this is divide the numerator(top number) by the denominator(bottom number) So you have one fifth, which is written as 1/5
1 divided by 5 is .2
ANSWER: .2
Hope this helped!!(:
Answer:
29/4
Step-by-step explanation:
37B. (x+3)(x+2)=x^2+5x+6
38. A (x-10)(x+6)
B (x+1)(x+2)
C (x-5)(x+6)
39. 5(x^2-9) = 5,x-3,x+3
Perpendicular to the y-axis means that it is a y=number
with no x in the equation
the point is given in the (x, y) form
(7, -12) which means the y value is -12
this means that your answer/equation should be
B
