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 heads (H)?



0.45


0.5


0.65


0.8

Answer 2

you have 9/20 heads so using a calculator what do you get?

Answer 3

0.45?

Answer 4

yes

Answer 5

Right, so what hippo exactly did was count the amount of times they got heads and divided by the total amount of trials being 20. So there 9 heads in total and remembering that \[Probability = \frac{ \text{number of favourable outcomes} }{\text {number of possible outcomes} } \] we have 9/20
