Answer:
P(B)=0.7
Step-by-step explanation:
When the events do not affect each other, they are known as independent events. In other words, two events are independent if the outcome of the second event is not affected by the outcome of the first event.
If A and B are independent events, the probability that both events will occur is the product of the probabilities that the individual events will occur:
P(A and B)= P(A)*P(B)
In this case, P(A and B)= 0.21 and P(A)= 0.30
Replacing:
0.21=0.30*P(B)
Solving:

<u><em>0.7=P(B)</em></u>
Answer:
<u>The value of x is 11 and CE = 40 and AC = 60</u>
Step-by-step explanation:
Δ ΑΒC ≅ Δ EDS, therefore we have that:
24 / 36 = 3x + 7 / 6x - 6
Solving for x,
24 * (6x -6) = 36 * (3x + 7)
144x - 144 = 108x + 252
144x - 108x = 252 + 144
36x = 396
x = 396/36
x = 11 ⇒ 3x + 7 = 33 + 7 = 40; ⇒ 6x - 6 = 66 - 6 = 60
<u>The value of x is 11 and CE = 40 and AC = 60</u>
<h2><em><u>correct answer: 1/33</u></em></h2>
I don’t know how to solve this but I think u have to use the fractions with the other numbers and multiply them then divide
The answer is C I’m pretty sure, it makes the most sense
