Answer:
Answer is 0.696
Step-by-step explanation:
The sum number of sets possible for no two students to have the same birthday in a class of 30 is:
=30 * (30-1)/2
= 435.
Now, there are 365 days in a year. Therefore, the probability of students having a birthday on a different date would be 364/365. Now there are a number of combination, to be exact 870 combinations.
So, the probability that no two students having the same birthday is:
(364/365)^435 = 0.303.
Now, the probability that two students would have their birthdays on the same equal date would be:
1-0.303 = 0.696 or 70%
Answer:
20.9-26.2 = -5.3 to the left (or 5.3 to the right)

Answer:
Step-by-step explanation:
Product means multiply
(10x^4y^2)(3xy3)
Numbers: 10*3 = 30
x: x^4 * x = x^5
y: y^2 * y ^3 = y ^ 5
Answer: 30x^5y^5
Powers don't multiply, they add. How confusing!
