Probability Mastery Test Review

EXPERIMENTAL or CLASSICAL Probability? After rolling a dice 20 times, Angelo said the probability of rolling a 5 is 1/6

• Experimental, because he actually rolled the dice

• Experimental, because he got a fraction

• Classical, because it's the correct probability

• Classical, because he wrote it as a fraction

EXPERIMENTAL or CLASSICAL probability? 13.5% of drivers pulled over in CT were black, according to a report by TrendReport.org.

• Experimental, because they used data of who was actually pulled over

• Experimental, because it's a percent

• Classical, because it's a percent

• Classical, because TrendReport.org is a legitimate source

EXPERIMENTAL or CLASSICAL probability? The probability of rolling a 3 with a regular, 6-sided dice is 1/6.

• Experimental, because they actually rolled the dice

• Experimental, because it's a fraction

• Classical, because it's a fraction

• Classical, because it's based on math

What is the probability of rolling a 2 or 3 with a regular 6-sided die?

• 1/6 + 1/6 = 2/12

• 1/6

• 1/6 + 1/6 = 2/6

P(3 or 2) =

• 1/2

• 2/3

• 5/8

P(3 and then 2) =

• 2/8*3/8 = 6/8

• 2/8*3/8=6/64

• 2/8 and then 3/8

From a bag of 12 marbles with 2 red marbles, 3 blue marbles, 6 yellow marbles, and 1 purple marble, find

P(purple and yellow, with replacement)=

• 1/12 * 6/12 = 6/144

• 1/12 + 6/12 = 7/12

• 1/12 and then 6/12

• 1/12 * 6/12 = 6/12

There’s a 37% chance it will rain today. What’s the percent chance it will not rain?

• 37%

• It's 50 - 50%

• 63%
