Acoin is tossed 20 times. it lands on heads 9 times. what is p(h) according to your experiment? write your answer as a fraction, decimal, and percent

9/20, 0.45 and 45%

Step-by-step explanation:

The problem states that every 20 times you flip a coin you get 9 heads. This means that the P(H) in a fraction would be 9/20. The decimal is a fraction but is out of a power of 10. to make it a decimal multiply both, the numerator and denominator by 5. This gets you 45/100. This is 0.45. A percent is a fraction out of a 100 which means the percent is 45%
