Suppose you flip a penny 50 times, with 28 tosses landing heads up. what percentage of the tosses would be heads and would percentage would be tails

28/50 would be heads. To convert to percent, first multiply the denominator and numerator by 2 to make the denominator 100 (since a percent is a value per 100).

28/50= 56/100= 56%

22/50 would be tails so apply the same process.

22/50=44/100= 44%

Final
Heads- 56%
Tails- 44%
