What is the theoretical probability of rolling an odd number on a 6-sided die?

1/6

1/3

3/6 or 1/2

0/6

In theoretical probability if I rolled a 6-sided die 12 times, how many 1's should you expect to roll?

In theoretical probability if I flipped a coin 20 times, how many heads should I expect to get?

(a)

I flipped a coin 20 times. There were 13 heads and 7 tails. Which best explains why the experimental probability differs from the theoretical probability?

There is something wrong with the coin because it should be 10 heads and 10 tails.

Theoretical probability is just a guess and the real probability of flipping heads should be 65% and the real probability of flipping tails should be 35%

If I were to continue flipping the coin to make a larger sample (50, 100, 1000 flips), the experimental probability should start to look more like the theoretical probability.

In a group of 75 students, 60 are seniors, 45 are male, and 24 are male seniors. Which shows the addition rule for calculating the probability of randomly selecting a senior OR a male?

$\frac{60}{75}\ +\ \frac{45}{75}\ -\ \frac{0}{75}$

$\frac{60}{75}\ +\ \frac{45}{75}\ -\ \frac{24}{75}$

$\frac{40}{60}\ +\ \frac{24}{60}\$
