Question

Vincent flipped three coins during a probability experiment. The outcomes of the first 40 trials are shown in the table.
Based on the information in the table, in how many of the next 120 trials will the outcome be exactly two of the coins showing heads?
A) 60
B) 87
C) 39
D) 48

Answer 1

Answer:

48

Step-by-step explanation:

There are 40 trials, 16 out of those 40 trials resulted in two heads and one tail, which is what we are trying to find out of 120..

To do that, find 16/40 which gives you 0.4%

Next multiply 0.4% by 120 and you will get 48.

Hope this helped!

Answer 2

The number of next 120 trials will the result should be 48.

Given that,

There are the first 40 trials.

The 2 heads and 1 tail should be 16 outcomes.

And, there are the next 120 trails.

So, the fraction should be

$= \frac{16}{40}$

= 0.40

Now the number of the next 120 trails should be

= 0.40 of 120

= 48

Therefore we can conclude that The number of the next 120 trials will result should be 48.
