Answer:
a = 162
Step-by-step explanation:
9 = 1/27 a +3
Subtract 3 from each side
9-3 = 1/27 a +3-3
6 = 1/27 a
Multiply each side by 27
6*27 = 1/27 a *27
162 = a
Answer:
2/3
Step-by-step explanation:
A = Student studying Math
B = Student studying Science
P(B|A) = P(A and B) ÷ P(A).
P(B|A) means the probability of event B given event A.
Given :
P(A and B) = 0.40.
Also P(A) = 0.60.
P(B|A) = 0.40 ÷ 0.60 = 2 ÷ 3.
So, the answer is 2/3.
