Question

A fair coin is flipped 10 times and the results are observed. The coin lands heads-side up 4 times.

What is the experimental probability of the coin landing tails-side up?

Answer 1

The experimental probability of the coin landing tails-side up is 60%.

Explanation:

The probability of it landing heads up is 4/10. You can use 4/10 to find how many times it landed on tails.

10/10 - 4/10= 6/10 now convert 6/10 into a percentage, 60/100=60%

Answer 2

Answer: 0.6

Explanation:

Given : the total number of times a fair coin flipped = 10

The total number faces on a fair coin (Tail/head)=2

Since, the number of times coin lands heads-side up=4

Then , the number of times coin lands on tails = 10-4=6

Now, the experimental probability of the coin landing tails-side up will be :-

`\text{P(Tail)}=\frac{\text{Number of times coin lands on tails}}{\text{Total number of times coin flipped}}\\\\=(6)/(10)=0.6`

Hence, the experimental probability of the coin landing tails-side up = 0.6
