Probability

Probability is measured using numbers from ____to ____

• 0 , 1

• 0, infinity

• adding

• multiplying

Answer explanation

 A probability that's close to 0 means something is unlikely to happen, such as correctly guessing a stranger's birthday. In fact, you're much more likely to guess a stranger's birthday 

incorrectly.

 The probability of guessing the birthday incorrectly is close to 1.

When determining probabilities, the possible results of an action are called 

• variables

• outcomes

• events

• kittens

Answer explanation

For example, if you roll a six-sided die, there are six possible outcomes. The die can land on 1, 2, 3, 4, 5, or 6.

An _________ is a set of those outcomes. If you roll a six-sided die, the outcomes of rolling a 4, 5, or 6 make up the event of rolling a number greater than 3.

• option

• multiplication

• event

• litter

The formula for probability is

P(event)= number of favorable outcomes

number of possible outcomes

• True

• Falae

Answer explanation

The probability of an event happening, written as P(event), is the number of favorable outcomes divided by the total possible outcomes. Favorable outcomes are the outcomes that make up the event. You can write P(event) as a fraction

If you combine two or more simple events, they are called?

• Simple events

• Compound events

• simple probability

• compound probability

Answer explanation

For example, rolling a six-sided die and then flipping a coin would be a compound event.

To find the compound probability of independent events you have to.....

• multiply everything

• add and then subtract

• I don't know

• multiply the probabilities of the simple events.

Answer explanation

If A and B are independent events, you can find the probability of both A and B happening using the formula P(A and B) = P(A) P(B)
