Question

EASY BRAINLIST
A coin was flipped 150 times. The results of the experiment are shown in the following table:

Heads Tails

90 60

Which of the following best describes the experimental probability of getting heads?

It is 10% higher than the theoretical probability.

It is 10% lower than the theoretical probability.

It is equal to the theoretical probability for this data.

The experimental probability cannot be concluded from the data in the table.

Answers

  1. It is 10% higher than the theoretical probability.
    Heads   Tails
    90         60
    probability of getting heads:
    (90/150)*100
    60%
    • 60% – 50% = 10% higher than theoretical probability.
    probability of getting tails:
    (60/150)*100
    40%
    • probability of getting heads is 10% more than tails.
    • Not equal.
