Answer:
(D)0.9836
Step-by-step explanation:
There are 365 days in a year.
Since each person has a different birthday:
- We can choose a birthday for the first person 365 out of 365 days.
- We can choose a birthday for the second person 364 out of 365 days.
- We can choose a birthday for the third person 363 out of 365 days.
- We can choose a birthday for the fourth person 362 out of 365 days.
Therefore,
P(4 randomly selected people all have different birthdays)
Answer:
27/200
Step-by-step explanation:
Knowing that:
A bag of tokens contains 9 red, 6 green, and 5 blue tokens. What is the probability that a randomly selected token is red and green?
Solve:
and = multiply
Total = 9 red + 6 green + 5 blue = 9 + 6 + 5 = 20
Total = 20 token
Thus,
There are 9 red and 6 green..
Hence,
9 out of 20 is red
6 out of 20 is green
Equation
9/20 × 6/20
Multiply Across:
9 × 6 = 54
20 × 20 = 400
54/400
Simplify
27/200
Therefore, the probability that a randomly selected token is red and green is 27/200.

Answer:
C
Step-by-step explanation:
Anything multipled by 6 will always be even, and anything multiplied by 4 will also always be even. Therefore, when we multiply (6x to the 4th)(4x to the 3rd), the answer will be even. However, 3 is odd, and an even number minus an odd number is ALWAYS odd.
