Answer:
There will be total 2048 parts of the given paper if James if able to fold the paper eleven times.
The needed function is
Step-by-step explanation:
Let us assume the piece of paper James decides to fold is a SQUARE.
Now, let us assume:
n : the number of times the paper is folded.
y : The number of parts obtained after folds.
Now, if the paper if folded ONCE ⇒ n = 1
Also, when the pap er is folded once, the parts obtained are TWO equal parts.
⇒ for n = 1 , y = 2 ..... (1)
Similarly, if the paper if folded TWICE ⇒ n = 2
Also, when the paper is folded twice, the parts obtained are FOUR equal parts.
⇒ for n = 2 , y = 4 ..... (2)
⇒
Continuing the same way, if the paper is folded SEVEN times ⇒ n = 7
So,
⇒ There are total 128 equal parts.
Lastly, if the paper is folded ELEVEN times ⇒ n = 11
So,
⇒ There are total 2048 equal parts.
Hence, there will be total 2048 parts of the given paper if James if able to fold the paper eleven times.
And the needed function is

Answer:
The number of people, of the twelve, who will win a prize is 5.
Step-by-step explanation:
In a standard deck of cards there are 52 cards.
The 52 cards are divided into 4 suits: Hearts, Diamonds, Spades and Clubs, each of 13 cards.
Each of the 12 people draws 2 cards from their standard deck of cards.
Compute the probability of selecting at least 1 diamond as follows:
P (At least 1 diamond) = 1 - P (No diamond)
The probability of selecting at least 1 diamond is 0.4412.
If a person draws at least 1 diamond he wins a prize.
The expected number of people who will win the prize is:
E (Wins a prize) = n × P (At least 1 diamond)
Thus, the number of people of the twelve who will win a prize is 5.
