The probability that the Cubs win their first game is 1/3. The probability that the Cubs win their second game is 3/7. What is t he probability that the Cubs win games?
2 answers:
We need to multiply these probabilities up. Indeed, we are talking about independent events. Then, the final answer is 1/3 * 3/7=1/7
The <em>correct answer </em> is:
1/7.
Explanation :
The two events, the Cubs winning their first game and the Cubs winning their second game, are independent. This is because the Cubs winning their first game does not affect the probability of the Cubs winning their second game.
Since the events are independent, to find the probability that both events occur, multiply the probabilities:
1/3(3/7) = (1*3)/(3*7) = 3/21 = 1/7

Answer:
A. 1/8
Step-by-step explanation:
m = rise/run
m = (y2-y1)/(x2-x1)
m = (-5- - 4)/(1-9)
m = (-5+4)/(-8)
m = (-1)/(-8)
m = 1/8

Answer:
x= (y-5)/2
Step-by-step explanation:
Isolate the x variable.
y= 2x +5
Subtract 5 from both sides.
y-5=2x
Divide both sides by 2.
(y-5)/2= x
4x^2 +15x + 13 tyats would be tour answrr
