Since the problem states "at least" we need to also find probability of 3 H or 4 H or 5 H
Now find the probability of flipping a head 4 times;
⁴
= (1/16)
Now probability of flipping a head 3 times: (4C3)(1/2)⁴ = 4/16
Probability of flipping a head 2 times; (4C2)(1/2)⁴=6/16
(1/16)+(4/16)+(6/16)=11/16
Probability of flipping a fair coin 4 times with at least 2 heads is 11/16.
Hope I helped :)

the answer in image three where right Right
The domain of a function is the set of input values the function can take
The domain is all set of real numbers
<h3>How to determine the domain</h3>
The expression is given as:
Factorize the numerator of the expression
Simplify: Cancel out the common terms
The above expression can take any value of x.
Hence, the domain is all set of real numbers

Answer:
She should order 10 orders of the 4-pizza deal from Peat's Pizza
Step-by-step explanation:
<u>Peat's Pizza deal:</u>
