Lesson Worksheet

Q1:

Two coins are tossed 76 times. The upper faces are observed, and the results are recorded in this table. Determine the experimental probability of getting two tails as a fraction in its simplest form.

Q2:

The table shows the results of a survey that asked 20 students about their favorite breakfast.

What is the probability that a randomly selected student prefers eggs?

Q3:

A biased coin was tossed 350 times and the number of tails observed was 178. Calculate the relative frequency of getting heads.
