Question

Randy was playing "Double Heads," a game in which he would flip two coins at a time. He recorded the number of times he flipped two heads at the same time. He flipped the coins 50 times, and there were 20 times when both coins landed heads up, which he recorded as 20/50. How does 20/50 compare to 50%?

Answer 1

Kindly check explanation

Explanation:

Total number of coin flips = 50

Number of times both coins landed head up = 20.

Hence probability of having two heads :

Probability = required outcome / Total possible outcomes

P(both heads up) = 20/50

Comparing 20/50 to 50%

We convert 20/50 to percentage :

(20/50) × 100%

0.4 × 100% = 40%

20/50 is equivalent to 40%

Hence, 40% is less than 50%
