Answer:
The expected number of times the cup will land on its side is 54 times
Explanation:
The expected number of times the cup will land on its side can be predicted using the data generated from the experiment.
The probability that a cup will land on its side is;
P(A) = number of times it land on the side N(A) / total number of trials N(T)
P(A) = N(A)/N(T) ....1
Given;
N(A) = 210
N(T) = 350
Substituting the values,
P(A) = 210/350 = 0.6
If alfie tosses the paper cup 90 more times what is the expected number of times the cup will land on its side
From equation 1;
Making N(A) the subject of formula.
N(A) = P(A) × N(T) ....2
P(A) = 0.6
N(T) = 90
Substituting the values;
N(A) = 0.6×90
N(A) = 54 times
