Types of probability/Independent & dependent events

If you are asked for the probability of tossing a coin and rolling a six sided die, how many outcomes are there?

• 12

• 8

• 6

• 20

Which two types of probability describes "Marian chooses a chip out a box of red and blue chips 25 times and the chip each time after drawing one. She draws a red chip 6 times."

• classical probability or theoretical probability

• empirical probability or experimental probability

• subjective probability or simulation

Which types of probability is described by "The probability of drawing a King out a standard deck of cards is 1 out of 13."

• empirical or experimental probability

• classical or theoretical probability

• subjective probability or simulation

A box contains 5 red chips, 7 blue chips and 3 green chips.

What is the probability of drawing a red chip?

• $\frac{1}{2}$

• $\frac{3}{14}$

• $\frac{1}{3}$

A box contains 5 red chips, 7 blue chips and 3 green chips. Find the probility that two chips are drawn, with replacement, and both are green (green and green)

• $\frac{3}{15}=\frac{1}{5}$

• $\frac{6}{210}=\frac{1}{35}$

• $\frac{1}{20}$

• $\frac{9}{225}=\frac{1}{25}$

A box contains 5 red chips, 7 blue chips and 3 green chips. Find the probility that two chips are drawn, without replacement, and the first is blue and the second is red.

•  $\frac{28}{210}=\frac{2}{15}$ 

•  $\frac{35}{210}=\frac{1}{6}$ 

•  $\frac{35}{225}=\frac{7}{45}$ 

In a deck of card two cards are drawn with replacement. What is the probabilty they both are Kings. (Draw a king, put it back, draw a king)

• $\frac{1}{2704}$

• $\frac{12}{2652}=\frac{1}{221}$

• $\frac{16}{2704}=\frac{1}{169}$

In a deck of card two cards are drawn without replacement. What is the probabilty they both are Kings. (Draw a king, put it back, draw a jack)

• $\frac{1}{2704}$

• $\frac{12}{2652}=\frac{1}{221}$

• $\frac{16}{2704}=\frac{1}{169}$

Drawing 2 cards from a deck without replacement, what is the probability that the first is a heart and the second is a black card?

• $\frac{1}{8}$

• $\frac{1}{4}$

• $\frac{1}{2}$
