Probability Outcomes and Events

Which is an example of theoretical probability?

• The probability of rolling a 4 on a die is 1/6.

• I flipped a coin and it landed on tails 2/10 times.

Which is an example of experimental probability?

• The spinner landed on three 7 out of 10 times (7/10)

• The probability of landing on tails is 1/2.

the probability of an event when that specific event will definitely happen

• certain

• impossible

• uniform

• non-uniform

the probability of an event when that specific event will definitely NOT happen

• certain

• impossible

• uniform

• non-uniform

If the probability of an event happening is unlikely, the chances of it happening are...

• greater than 1/2

• less than 1/2
