Answer:
just put a vertical line through it, in front of the 7,8,9,10 and behind the 7,1,0,00. I couldn't do that on here.
Step-by-step explanation:
7 -7
8-1,5,8,9
9-0,2,5,7,
10-00,00
Set up the two events
A = first card is a 9
B = second card is a 9
The probability for event A is
P(A) = 4/52
because there are four "9" cards out of 52 total
If event A happens first, and B follows, then the probability is
P(B|A) = 3/51
because there are 3 nines left over out of 52-1 = 51 total left over
No replacement has been made
The notation P(B|A) means "probability of event B given that event A has happened"
Multiply the probabilities
P(A and B) = P(A)*P(B|A)
P(A and B) = (4/52)*(3/51)
P(A and B) = (4*3)/(52*51)
P(A and B) = 12/2652
P(A and B) = 1/221
P(A and B) = 0.00452488687782
Rounded to 4 decimal places, the approximate answer is 0.0045
The exact answer as a fraction is 1/221
Answer:
Your answer is mean absolute deviation.
Step-by-step explanation:
40 winds. To be exact 40.2336 winds. But that’s not really possible so I would say 41 winds.
