Answer:
75%
Step-by-step explanation:
P(A|B)= P(B and A) / P(A)
P(B and A) = .3 + .10 = .13 P(A)= .3
So,
P(A|B)= .13/.3
P(A|B)= 0.43333...
Answer:
I believe 25%
Step-by-step explanation:
There are four equally likely outcomes: HH, HT, TH and TT. Of these, one of these match the criterion given ("the first will come up heads and the second tails”). So the probability is 1/4= 25%.
Answer: -3 = k
Step-by-step explanation: y/x = k is the equation.
Okay so you plug in y into that equation and x also. You should have the equation -9/3 = k. All you do is solve! You should get -3=k. I hope this helped! :D
