Question

A coin is tossed 20 times. The outcomes H (for heads) and T (for tails) are recorded:

H T H T T T T H H T T H H T T T H H H T

What is the experimental probability of getting tails (T)?
0.45
0.55
0.65
0.8

Answer 1

0.55

Explanation:

Answer 2

After all 20 tosses of the coin, a tail was recorded 11 times. We can write this as 11/20.

To convert this into a decimal, we simply multiply the numerator and denominator by 5 so that the fraction is out of 100, giving us 55/100.
When we do the sum of 55 ÷ 100, we get the answer of 0.55.

I hope this helps!
