QUESTION: 21

A drawer holds 4 red hats and 4 blue hats. What is the probability of getting exactly three red hats or exactly three blue hats when taking out 4 hats randomly out of the drawer and immediately returning every hat to the drawer before taking out the next?

1/8
1/4
1/2
3/8
7/12

Answer(s): C

Explanation:

Getting three red out of 4 that are taken out has 4 options (4! / (3!*1!)) each option has a probability of (1/2)4 since drawing a red or blue has a 50% chance. 4*1/16= 1/4 to get three red hats. The same goes for three blue hats so 1/4+1/4 =1/2. The correct answer is C.

Here, it is enough to calculate the simple interest of 8% per year.
$2,400 x 8/100 x 1 = $192. Since we are calculating as a compounded rate, the interest should be a bit higher or C as the correct answer.

X is a prime number bigger than 10. Also, Y = X+X3+X5+X7. What is definitely true about Y?

Y is a prime number.
Y is odd.
Y is even.
Y is divisible by 3.
Y is divisible by 7.

Answer(s): C
