-7y - 6y³ + 2y + 4y³ - 5 -1 - 2y³
= -4y³ - 5y - 6 //Combine like terms.

Every handshake takes 2. If no one shakes hands twice with another, there are 10+1 total people shaking hands (11).
Name them 1 thru 11. Make a line and 11 goes down the line and shakes 10 hands and then leaves. 10 then shakes 9 hands and leaves. 8 then shakes 7 hands and leaves. Etc. 2 shakes hands with 1 and leaves. 1 just leaves.
11— 10 hs
10— 9 hs
9— 8 hs
8— 7 hs
7— 6 hs
6— 5 hs
5— 4 hs
4— 3 hs
3— 2 hs
2— 1 hs
1— leaves
Total handshakes 55, total people 11.

Step-by-step explanation:
Answer:
48%
Step-by-step explanation:
The conditional probability definition applies.
P(med | cold) = P(med & cold) / P(cold)
The probabilities are the table numbers divided by the total of all numbers in the table (100). Since that dividend is the same for all, we can basically ignore it and just use the table numbers.
P(med | cold) = (12)/(8+12+5) = 12/25 = 48/100
P(med | cold) = 48%
