Question

When a coin was tossed, it came up heads 12 times and tails 8 times.

What percent of the time did it come up tails?

Answer 1

It’s 1/2 (the probability of getting either heads or tails) to the power of 8 (for 8 tosses).

1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2=1/128=0.00390625 =40%

Explanation:

Answer 2

Answer: 40% of the time the coin came up tails.

Explanation:

The coin is tossed 20 times. Of those 20 times, it came up tails 8 times (8/20). 8/20 = 0.4 = 40%
