Question

A spinner consists of a circle divided into four equal sectors. Each sector has a different color.

The probability of the event is....

Can the event be considered unusual?

A. No, because the probability is 0.10 or less.

B.No,because the probability is greater than 0.05greater than 0.05.

C.Yes, because the probability is greater than 0.10.

D.Yes,because the probability is 0.05 or less0.05 or less.

A probability experiment consists of rolling a four-sided
die and spinning the spinner shown at the right. The spinner is equally likely to land on each color. Use a tree diagram to find the probability of the given event. Then tell whether the event can be considered unusual.Event: rolling a 2

Explanation / Answer

4 sided die. will have a 1/4 probability to get 2.

There are again 4 colors, therefore, 1/4 probability that BLUES will come.

So, event a 2 and the spinner landing on blue is:

1/4 *1/4
=1/16
= .063

Event is unusual when p is less than .05, which is not in this case.

Answer is B. No. bcz p = .63>.05
