13/28+17/20=−13/28+17/20=27/70
*Hint: The formula for finding the surface area of a rectangular prism is SA = 2 (wh + lw + lh).
Now, just plug in and solve.
SA = 2 [(10)(8) + (12)(10) + (12)(8)]
SA = 2 (80 + 120 + 96)
SA = 2 (296)
SA = 592.
The surface area of Rita's room is 592 feet squared.
Answer:
Step-by-step explanation:
From the given information:
Let represent as the first player getting an ace
Let to be the second player getting an ace and
as the second player not getting an ace.
So;
The probabiility of the second player not getting an ace and the first player getting an ace can be computed as;
Let's determine the probability of getting an ace in the first player
i.e
To determine the probability of the second player getting an ace and the first player getting an ace.
Thus, the conditional probability that the second player has no aces, provided that the first player declares affirmative is:
Therefore;
for n= 2
for n= 10
for n = 100
