The answer is 3.45 (C) because 1.15 x 3 = 3.45
D is the best pick ok your welcom
The value of the missing probability is:
P(A) = 1/5
So the correct option is D.
<h3>How to find the missing probability?</h3>
First, we know that:
P(A∩B) = probability that events A and B are true = 3/100
And we also know that:
P(B|A) = probability that event B is true given that event A is true = 3/20
Here we have the rule:
P(A∩B) = P(B|A)*P(A)
Replacing the first two:
3/100 = (3/20)*P(A)
Solving for P(A), we get:
(3/100)*(20/3) = 1/5 = P(A).
So we conclude that the correct option for the missing probability is the one in option D.

Answer: The mean and variance of Y is $0.25 and $6.19 respectively.
Step-by-step explanation:
Given : You and a friend play a game where you each toss a balanced coin.
sample space for tossing two coins : {TT, HT, TH, HH}
Let Y denotes the winnings on a single play of the game.
You win $1; if the faces are both heads
then P(Y=1)=P(TT)=
You win $6; if the faces are both heads
then P(Y=6)=P(HH)=
You loose $3; if the faces do not match.
then P(Y=1)=P(TH, HT)=
The expected value to win : E(Y)=
Hence, the mean of Y : E(Y)= $0.25
Variance = ![E[Y^2]-E(Y)^2](https://tex.z-dn.net/?f=E%5BY%5E2%5D-E%28Y%29%5E2)
Hence, variance of Y = $ 6.19
Answer: I think it’s 22 May 2021
Step-by-step explanation:-
First Step ) August 2020 + 9 Months = May 2021
Second Step ) 4 + 7*2 ( two weeks has 14 days ) or 4 + 7 + 7 = 18
Third Step ) 18 + 4 Days Later = 22
So final answer would be 22 May 2021.
Hope it helps, Good Day! And happy reading
