Answer:
Estimated probability
Step-by-step explanation:
In this question Emil estimates the probability of 2 or more heads coming up in 3 coin flips.
He has a computer which randomly selects 0 or 1 three times, with 0 representing heads and 1 as tails.
From the results shown we will select the preferred events of getting 2 or more heads, means results having 2 zeros or more than 2 zeros.
Number of preferred events are = 5
And total events are = 12
Therefore estimated probability =
Probability
Therefore answer is

To do this, we're going to use the order of operations (PEMDAS):
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
First let's do parentheses, there isn't anythig in parentheses we need to simplify, so we can skip this step.
Next let's look for exponents. I see we have a so let's replace that with
:
Now let's look for multiplcation. We know that things that are right next to eachother in parentheses represent multiplcation, so let's simply this more:
And now we're left with a simple problem we know how to solve.
