Rina Flipped a coin twenty times she flipped heads 4 times and tails 16 times what is the experimental probability that Rina will flip heads in her next flip?

pls answer asap and pls explain but not to much THANK U

Assuming that all of the other variables when flipping the coin is constant. The experimental probability that Rina will flip heads in her next flip is 20%.

Step-by-step explanation:

Experimental Probability is the probability solely based on the results of the previous experiments done.

In this case the results of the previous experiments is 4 times landing on heads and 16 times landing on tails.

With this info, and with the question asking for the experimental probability of heads in her next flip, we can then set up a "proportion" using the number of times experimented (20 times; because 4 heads + 16 tails = 20 total times experimented) and the number of times it actually landed on heads in the past (4 times).

The proportion should be set up with the total number of times experimented the denominator and the number of times it landed on heads as the numerator.

So, the proportion should look like this,

4/20 = ___

evaluating the expression, in terms of percentage we get 20%

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
