Question

What is the experimental probability that at least one of the coins landed on heads? Express the probability as a decimal.

Answer 1

The answer is 50% because to find the probability of 3/6 which is the even numbers that add up to 50 so 3/6 is equal to 1/2 and 1/2 of 100 is 50

so your answer is 50%

Answer 2

Answer with explanation:

It is given that number cube that is having number from (1 to 6) is rolled hundred times.

From the table it can be seen that,

→2 = 18 times

→ 4= 11 times

→6 = 21 times

→P = Probability

`P(2)=(18)/(100)\\\\P(4)=(11)/(100)\\\\P(6)=(21)/(100)`

⇒ P(Even Number)

`=P(2) + P(4) +P(6)\\\\=(18)/(100)+(11)/(100)+(21)/(100)\\\\=(50)/(100)\\\\=(1)/(2)`

Required Probability in terms of Percentage

`=(1)/(2) * 100\\\\=50`

= 50%
