What is the experimental probability of heads?

Short Answer

Expert verified

The experimental probability is 0.25.

Step by step solution

01

Step 1. Define the meaning of simulation.

Simulations are used to perform experiments that would be difficult or impossible to perform in real life.

02

Step 2. Define the meaning of experimental probability.

The experimental probability is the ratio of the number of times an outcome occurs to the total number of events or trials.

Experimental probability=蹿谤别辩耻别苍肠测鈥夆赌塷蹿鈥夆赌塧苍鈥夆赌塷耻迟肠辞尘别迟辞迟补濒鈥夆赌塶耻尘产别谤鈥塷蹿鈥夆赌塼谤颈补濒蝉

03

Step 3. Determine the experimental probability of heads.

Observe the given table.

The frequency for heads=25

The frequency for tails=75

So, the total number of trials=25+75=100

To find the experimental probability of heads, divide the frequency of heads by the total frequency.

So, the experimental probability is

=25100=0.25

Therefore, the experimental probability is 0.25.
