X = 3

2X = 6

6^2-6<-4X

6^2 = 12

12-6<-4X

12-6=6

6<-4X

-4X = -12

6<-12

You flipped a coin 50 times and got 23 heads.What is the experimental probability of getting a head? Write your answer as a frac

Studentka2010 [4]

Answer:

$\frac{23}{50}=0.46=46$ %

Step-by-step explanation:

Experimental probability is the actual odds produced from an event. Probability is typically expressed as a fraction of the number of desired outcomes (numerator) over the total number of outcomes (denominator). In this case, the desired outcome is getting heads on a coin flip (23) and the total outcomes is the number of times you flipped the coin (50). Represented as a fraction:

$\frac{23}{50}$
