Answer: 6

Step-by-step explanation: So there is 4 people and lets say I'm one of them, so I shake hands with 3 people, that's 3 handshakes, then one of those 3 people shake hands with the other 2, that's 5 handshakes, and then the last 2 shake hands with each other since they haven't, so that's 1 more which means 6 handshakes.

there are 4 red, 6 yellow and 6 blue socks in the drawer. if the sock is not replaced after it is drawn,what is the probability
ollegr [7]
Total amount: 16

Red socks: 4

Probability of picking a red sock 4/16

If we take a red sock out and do not replace it, we are left with a total of 15 socks.

Blue socks: 6

So the probability of picking a blue sock will be 6/15

Multiply:

4/16 * 6/15 = 24/240 = 1/10
