Answer:
12/15 as he has already had 15 outcomes.
Step-by-step explanation:
<span>The first person can have any birthday. That gives him 365 possible birthdays out of 365 days, so the probability of the first person having the "right" birthday is 365/365, or 100%.The chance that the second person has the same birthday is 1/365. To find the probability that both people have this birthday, we have to multiply their separate probabilities. (365/365) * (1/365) = 1/365, or about 0.27%.</span>
20 hours. You find this by dividing 150 by 10 and then multiplying that by 2.
The first one is the second one. t(n)=20n+480
Question 4: is the first one t(n)=8n+15
