Questions d'entretiens - Intern

From what I understand the answer is 5/16? From a decision tree, we can see that there are 2^5=32 possible outcomes of flipping a fair coin 5 times. The number of times we get two specific heads in these 5 flips is 5C2=10. P(2 heads)=(number of outcomes in which 2 heads occur)/(number of total outcomes)=10/32=5/16

it saids atleast 2 heads. That is P(3)+P(4)+P(5) heads. The answer is 0.5

the way I thought best

Through questions like this, interviewers are mostly trying to test your skillset (and its relevance to the role) as robustly as possible, so be prepared for multiple offshoots and followups. It could be a useful exercise to do mocks with friends or colleagues in Datadog to get a real sense of what the interview is actually like. Alternatively Prepfully has a ton of Datadog Software Engineer Intern experts who provide mock interviews for a pretty reasonable amount. prepfully.com/practice-interviews
