Question

Calculate the probability of getting 12 heads in 20 attempts from a fair coin.

Answer 1

Answer:

3:5

Explanation:

probability= 12/20

= 3/5

therefore probability of getting heads is 3:5

Answer 2

Your answer is 3/5.

Total number of getting heads=12.

Total number of coin toss =20.

$P(E) = \frac{Total number of getting heads}{Total number of coin toss} \\ = \frac{12}{20}\\= \frac{3}{5}$
