The charity will receive $ 11
<h3><u>
Solution:</u></h3>
Ken earned $176 from his part-time job this summer
Amount earned = $ 176
He spent 25% of his money on games
Therefore,
Money spent on games = 176 - 25 % of 176
He is going to donate 1/4 of the remaining money to charity
Reamining amount = 176 - 132 = 44
Therefore,
Thus he gave $ 11 to charity

Answer:
the probability that Christine fails the course is 0.425
Step-by-step explanation:
A = Christine fails the course
B = Christine finds a tutor at such short notice
P(B) = 0.75
P(A|B) = 0.35
P(A|B') = 0.65
by total probability theorem
P(A) = P(A∩B) + P(A∩B')
by definition of intersection probability
P(A) = P(A|B)P(B) + P(A|B') P(B') = 0.35*0.75 + 0.65*(1-0.75)=0.425
Answer:
Not, 1
Step-by-step explanation:
The complement of an event denoted as A', can be interpreted as not A. This means that elements not belonging to a A. In probabilistic term, if we have an event A, the complement is f A is the probability that event A does not occur.
The sum of an event A and its corresponding complement must equal to 1.
This is given by the complement rule ;
P(A) + P(A') = 1
Hence, P(A') = 1 - P(A)
