Answer 1

Answer:

3)  likely

4)  1/2; equally likely

Step-by-step explanation:

3) You are being asked to translate a numerical value to a subjective statement. There are no hard-and-fast rules for this. Generally, the meanings of the terms you're asked to choose from are ...

• impossible: probability is zero. The outcome cannot occur.
• unlikely: chances are less than even; often, "unlikely" means a probability of 10%, 5%, 1% or lower, depending on the context.
• equally likely: probability is near 50%
• likely: more likely than not. Again, this depends on the context.
• certain: probability is 1. There is no chance the outcome will not occur.

An 80% probability is greater than 50%, so might reasonably be called "likely."

___

4) a. Four of the eight numbers are even, so the probability of obtaining an even number at random is 4/8 = 1/2.

  b. A probability of 50% might reasonably be called "equally likely", as the probability the event will occur is equal to the probability it won't.
