Probability that the nth person believes the rumor

The probability that a randomly chosen person will believe a rumor about a politician's extramarital affair is 0.6. People from the public are randomly selected independently of one another at random. It is known that only one person between the first two selected believes the rumor. What is the probability that the sixth person who hears the rumor is the third person who believes roughly.

I don't understand why the answer is 3C2 * (0.6 ^ 2) * (0.4 ^ 2).

Who still believes Trump owes all Democrats an apology?

On February 28, 2020, Trump told supporters of a rally in South Carolina that the novel corona virus was a joke that Democrats had made to make it look bad! He was quoted as saying, "Now the Democrats are politicizing the corona virus." "You have no idea, you can't even count your votes in Iowa. This is your new joke!" I believe Trump owes all Democrats a public apology after lying and accusing Democrats of joking to do further harm to his presidency! Who else feels that way?

John Kelly, former Trump chief of staff, believes in John Bolton and believes that impeachment witnesses should be heard …?

Kelly says he hasn't attended any of these meetings. Yes, however, witnesses should be heard. Kelly was the last chance for less turmoil in the White House, and what he says should be listened to carefully. He even warned Trump not to be charged if he didn't follow the rules. He was right.

Woocommerce believes that unsold items are for sale

We update the prices directly in the database. Is there a kind of field that indicates whether an item is for sale or not? We have tried several plugins that allow us to display sales items. These always contain products that are not for sale. My theory is that because we update the prices directly in the database and not in the backend, we will miss something if we remove the selling price. I tried to clear transients, and that does not work.

Thanks for your help.

Replication – MySQL believes that master and slave have the same server ID, but not

Attempt to set up MySQL to perform one-way replication. I set the master to server_id = 1, a replication user setup, binary logging enabled, slave_server_id = 2, and connected and waiting for an event. I also use the workbench.

However, the master server has the following error …

Fatal Error: The slave I / O thread is stopped because master and slave have the same MySQL server IDs. These IDs must be different for replication to work (or the --replicate-same-server-id option must be used on the slave, but this does not always make sense, please read the manual before use).

I can not find a reason for this mistake. I've seen dozens of tutorials, manuals, and so on, and none of them tell me what's going on.

Who believes that Trump will destroy Elizabeth Warren, Julian Castro and Kamala's Ghetto Harris in a debate?!?

Trump is the worst debater I've ever seen in a major political appointment. As stated in the anonymous poster, it is not a debate to just throw random insults and direct lies. Attacking the enemy, attacking the dignity, attacking the political process, attacking the truth, and it has nothing to do with trying to convince the opponents to just beat. It may be effective for certain people, but it is not really a debate.


Who honestly believes that Don Jr. did not tell his father that Russians want to talk to him or who was in his own tower in June or not?

And what if he had done it? Is this Hillary who stole the election the same?

And please, do not even try the "Lies" bullshit.

I have never sent a classified ad
I only used one part
I remember when I landed under sniper
A video caused this attack

Only STFU, right?
