Question

When a particular type of thumbtack is​ dropped, it will land point up ​(A flat-top thumbtack resting on its flat top​) or point down ​(A flat-top thumbtack resting on the edge of its flat top and the tip of its needle​). This experiment was repeated times with the following​ results: point​ up: ​48 times; point​ down: 52 times.
a. What is the experimental probability that a particular type of thumbtack will land point​ up?

b. What is the experimental probability that a particular type of thumbtack will land point​ down?

c. If the experiment was tried another 100 times would the same results​ occur? Why?

d. Is it expected that nearly the same results occur on a second​ trial? Why?​

Answer 1

Answer:

0.48

0.52

No

Yes

Step-by-step explanation:

Result of experiment :

Point up = 48

Point down = 52

Total number of trials = 100

Recall :

Experimental probability = number of outcomes / number of trials

1.)

P(Landing point up) = 48 / 100 = 0.48

2.)

P(Landing point down) = 52 / 100 = 0.52

3.)

The same result will not occur has the outcomes of trials aren't fixed.

4.) Yes, nearly the same result could occur on the second trial, as the number of possible outcubes are just 2 and the number if trials is high.
