Question

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

Answer 1

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

$P(2)=\frac{18}{100}\\\\P(4)=\frac{11}{100}\\\\P(6)=\frac{21}{100}$

 ⇒ P(Even Number)

          $=P(2) + P(4) +P(6)\\\\=\frac{18}{100}+\frac{11}{100}+\frac{21}{100}\\\\=\frac{50}{100}\\\\=\frac{1}{2}$

Required Probability in terms of Percentage

           $=\frac{1}{2} \times 100\\\\=50$

    = 50%  

Option A      

Answer 2

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%
