I'm assuming you meant to say
P(A) = 2/3
P(A and B) = 1/3
If that is the case, then A and B are independent if and only if the following equation is true
P(A and B) = P(A)*P(B)
So we multiply P(A) and P(B) to get the value of P(A and B). We don't know what P(B) is, but we can use algebra to find it
-------------------------
P(A and B) = P(A)*P(B)
P(A)*P(B) = P(A and B)
(2/3)*P(B) = 1/3
P(B) = (1/3)*(3/2) .... multiply both sides by the reciprocal of 2/3
P(B) = (1*3)/(3*2)
<h3>P(B) = 1/2 is the answer</h3>
------------------------
If P(B) = 1/2, then
P(A and B) = P(A)*P(B)
P(A and B) = (2/3)*(1/2)
P(A and B) = (2*1)/(3*2)
P(A and B) = 1/3
Which is the given probability for both events happening. This confirms we have the correct P(B) value.
Answer:
4/1 or 4
Step-by-step explanation:
The GCF of 14 and 22 is 2.
14: 1, 2, 7, 14 (1 × 14 = 14) (2 × 7 = 14)
22: 1, 2,11, 22 (1 × 22 = 22) (2 × 11 = 22)
The greatest number that both of the sets share is 2.
(3+1)/(0+3)= 4/3
the answer to the question is 4/3
