Question

Each of three friends flips a coin 36 times. Angel records "tails" 20 times. Michael records "tails" 17 times. Fernando records "tails" 23 times. Find the relative frequency with which each friend records "tails". Write each as a percent rounded to the nearest whole percent.

Answer 1

Given:

Total times flipped the coin= 36 times

Angel recorded tails = 20 times

Michael recorded tails = 17 times

Fernando recorded tails = 23 times

To Find:

1. frequency of each friend to record tail
2. percentage(rounded) of recording tail of each friend

Step-by-step explanation:

1. frequency of each friend to record tail

for angel,

frequency to record tail = no. of times recorded tail/total times coin flipped

= 20/36

= 0.55

for Michael,

frequency to record tail = no. of times recorded tail/total times coin flipped

= 17/36

= 0.47

for Fernando,

frequency to record tail = no. of times recorded tail/total times coin flipped

= 23/36

= 0.63

1. percentage(rounded off) of recording tail of each friend

for angel,

percentage to record tail

= no. of times recorded tail/total times coin flipped × 100

$=\dfrac{20}{36} \times 100$

= 55.5  ≅ 56%

for Michael,

percentage to record tail

= no. of times recorded tail/total times coin flipped × 100

$=\dfrac{17}{36} \times 100$

= 47.2  ≅ 47%

for Fernando,

percentage to record tail

= no. of times recorded tail/total times coin flipped × 100

$=\dfrac{23}{36} \times 100$

= 63.8 ≅ 64%
